Buying things on the Internet, such as books, air tickets and groceries, is becoming more and more popular. Do the advantages of shopping in this way outweigh the disadvantages? Nowadays, with the huge increase in using the internet and websites, the popularity of internetshopping has experienced a drastic growth in the last decade, which has become an inseparable part of people’s life. Despite the drawbacks of this kind of shopping, it seems that the benefits of using the internet for shopping outweigh the disadvantages. Comfortable buying seems to be the first gift of online-shopping, in other words, the main difference of buying on the internet and shopping from stores in person is the convenience. For example, by pushing just several buttons you can do your errands without going anywhere. Moreover, saving time seems to be another precious achievement of buying on the internet. Consider the situation that where someone would be running out of time if he they wanted to go and buy an air ticket or another critical purchasing, but he they can buy the ticket in just a few seconds. Investigating the products that someone tends to buy is a huge step on in/toward online-shopping. The consumer takes his time and easily reads everything about the products, compares it with the other ones, and searches as much as he needs. On the other hand, besides the numerous advantages of purchasing online, the drawbacks cannot be ignored. Online frauds with phishing seem to be the main problem of online shopping. Every day lots of people are trapped on the internet by cyber scammers and lose their money. Take the example that where someone would not pay decent attention to the web site that they are using to pay the money for their purchases and submit their credit card information on a wrong portal. Moreover, sometimes the procedure of online-shopping is too complicated, especially for the one who is not familiar with the internet and using websites, that which cause a lot of troubles for both consumer and seller. Overall, in my opinion, in spite of the risks of purchasing online, saving time and the convenience of buying on the internet are completely worthwhile.

CUsing animals to test the safety of cosmetics or drugs used for medical reason is never acceptable. To what extent do you agree with this statement? ------------------------------------------------------------------------------------------------------------------------------------ Nowadays, despite the efforts being put into justifying the value of exploiting animals for medical and cosmetic intentions, there is still a bitter conflict as to whether this approach is a rationale and ethical one. As far as I am concerned, the use of laboratory animals as experimental subjects can be acceptable in the medical field but not in cosmetic. Given that under no circumstances do animal deserve to suffer, skeptics declare that not only does animal testing violate the bioethics rules, but it also should be considered illegal and be put out of use. Moreover, they might refer to alternatives to animal testing, including cell and tissue culture, by which it is possible to replace and refine this method. On the other hand, advocates might support it with a couple of reasons. Before carrying on, it is noteworthy that this issue in the medical context is poles apart form that in the cosmetic context in that while the former can be justified under rigorous precautions, the latter cannot be given any reasonable grounds. Animal usage for testing beauty products is a direct repercussion of the consumerism culture and fashion. This is why it can be utterly omitted. By contrast, as for their usage for examining drugs, we must bear in mind that had scientists not experimented on animals, a considerable number of human beings would have succumbed to various fatal diseases. Firstly, although alternative methods do exist, animal testing is still the most accessible and fiscally acceptable one since other methods are extremely expensive as well as not widely available in many laboratories. Secondly, up to the present time, mammalian species can provide the closest environment to human physiology, hence their extensive use over cell or tissue culture. Thirdly, as against the widely held belief about the cruelty of these experiments, they are being conducted under strict ethical rules with the aim of mitigating animals’ suffering. the main conclusion to be drawn is that even though animal testing is under fire, and probably will remain an ethical dilemma, in this write’s view not only can it be justified for on medical grounds, but it is also still the most sensible approach. 356 words

Computer games are very popular for all ages and nationalities. Parents think this has little educational value and it will be harmful for children. To what extent do you agree or disagree? There is no doubt that computers play a a vital role in lisure and training activities. While the role of education and training are is growing in this rapidly changing world, orthodox parents believe that if pupils apply themselves and try their hardest at school, then they will increase their opportunity for higher educations and better jobs in the future such a compatitive world. I guess, like many other aspects of modern technologies, computer games are a doble edge sowrd and can either both assist a better education or negatively affect itnot. In on one hand, addictin to electronic gadgets are is becoming a common problem phenomena phenomenon of modern socieries and which engading wast stratumstrata; from governments to parents as well as police officers to teachers. The youth are more profesional in computer gaming than the elderlies, who can notcannot supervise them, . therforetherefore, family value have no space to germinate there. The threat is that the main aim of computer game companies is to make money and so they do their best to make gimmiks rather than training. These games are designed to appeal to the lowest common denominators and consequently has less educational value. On the other hand, vitrual networks are said to be the pillar of future education. The Recent pandemic of Covid 19 has hightended the paramont importance of electronic games in education. Instilling appreciated moral ethics, boring mathematic furmulas and litriture in childerens’ minds is the latent underlying/embedded dutiy of useful video games . As an impartioal educated individual, I guess, the compures games are inseparatable part of our lives but the main question is that wheather individuals can be led into suitable games which per se are valuable and suitable for their age. Concerning the complexity of culture and technology, I think capable specialiez orgnization can take the helm atof the chaotic sea of computerized games to make take the best advantages of games.

darya atighi 11:45 AM (42 minutes ago) to me Nowadays, many families have both parents working. Parents believe other family members like grandparents can take care of their children, while others think childcare centres provide the best care. Discuss both views and give your own opinion. Nowadays most of the parents are too much involved with their works and need some help to takeing care of their children. Some people think childcare centres and grandparents can help parents to take care of their children. I would like to discuss both views and give my own opinion about this subject. I believe that parents should streak strike a balance between their work and the time that they should spent spend with their children. On the other hand, some of them have lots of responsibility in work and they cannot reduce their work hours. The best idea for those parents is to entrust their children to their grandparents because grandparents are part of the family and they are more common with their grandchildren’s desire and are more compassionate about them and they can spend more time with them. But in childcare centres there are more children exist and the teacher should have eyes on the other ones too. However, some of the children does not have any grandparents because they are dead our or they are too old to care for their grandchild. I in this circumstance the only choice they have is entrust their children to childcare centres. It is not a bad idea because sometimes these places develop child creativity in different things aspects/areas/subjects . But also it has drawbacks too because maybe other children bullyied to our child and our child gets depressed if this happened to them in at a low age. In conclusion, i think parents should consider some time to spend with children by ourselves to give them our their love but for the second choice we can get help from grandparents and childcare centres.

The growth of online shopping will one day lead to all shops in towns and cities closing. Do you agree or disagree? These days, the number of online markets has increased significantly, and they have captured a considerable proportion of daily transactions. The majority of purchasers especially the youngsters are passionate to buy their requirements through the online shops and this trend have has some ‘devastating impacts on the traditional shops and they are likely facing a sort of bankrupts bankruptcy in near future. However, although this new approach of ordering commodities brings several problems for the old shops, it provides many rewarding facilities for the purchasers which are the reason for this impressive popularity. Online shops could provide purchasers to save their time as it is a crucial matter in modern-day cities. Additionally, online markets are more often offer competitive prices in comparison to the traditional ones, since they do not have not to pay for rent or other expenses of keeping the place. Consequently, they could convince consumers more easily by their enticing prices. Moreover, the consumers could be aware of the quality of their required item by just reading the other purchasers’ opinion on the website instead of visiting real shops and asking their sellers about their products while we all know that “every cook praises his own broth”. Therefore, it seems that online marketing is not only a productive opportunity for online shops but also brings lots of benefits in terms of quality and prices for clients. On the other hand, this sheer number of online markets has ledleads to numerous repercussions on the traditional shops and they mostly have encountered financial problems. Although they have strived and took taken any measures to keep themselves afloat/prosperous in this unequal competition, they have mostly failed and are struggling with a lot of problems. It is notable that modern technology and online marketing as one of the subcategories of it, practically affects every aspect of our life and traditional markets are not far from this trend. In conclusion, there are several solutions to mitigate mitigating such drawbacks. the sales experts believe that the owner of traditional businesses and chain stores should built build up their online shops as well as their available shops. Furthermore, the more competitive price the more people are attracted, so they have to provide valuable discounts for their consumers in order to persuade them to remain as their clients.

The government now plans to establish some car-free zones in the center of the city. Some like this plan for they believe it can help eliminate traffic congestion, while others dislike it because not being able to reach places like stores and restaurants by car is very inconvenient to them. What do you think of this plan and why? Nowadays, everyone in a family who can achieve a driving license purchases a car. As a result, there would be lots of vehicles with an one single individual in itthem. Considering the restrained restricted roads in most of the cities, this leads to a dramatic city issue as we known of traffic. Governments are addressing the issue with different approaches. Whether they are functional or acceptable by citizens has always been a moot point. The recent heated debate around the subject is the new plan in which the government has been defined some city areas as car-free which has given rise to the dissatisfaction and unsatisfactory of a group of residents. Considering the traffic detrimental effects on the environment, I do agree with the proposed plan. First of all, we need to know the negative results of traffic congestions of which most important is the air pollution. Air pollution is the origin of numerous health problems such as strokes and heart diseases and lung-disfunctions. Secondly, heavy traffics plays a main role in wasting the precious time of people and leads to people feeling more exhausted. the traffic problem must be resolved and this is crucially urgent. There can be various solutions and one of them is to make people eager people to use more public transportation rather than using their own cars. However, people mostly resist against the plan because of the convenient convenience that the personal transportation may have for them. In this situation the government can interfere by some legislations such as banning the cars in city centers especially during the day. At first not only might this plan make people unhappy but also can result in some disobeying/disobedience. Police must be in charge and set/impose some fines in order to control the situation. In the long-term, however, people will recognize the positive aspects of the obligatory, namely a clear sky and breathable pleasant weather and less time consumption wasted/lost in traffic. In conclusion, I am definitely in favor of such plans for use using more public transportation instead of personal vehicles in order to constraint limit using fossil fuels which is a main reason for air pollution and its related defects. Moreover, we have a responsibility to preserve our planet for the future generation.

In some countries, owing a home rather than renting one is very important for people. Why might this be the cases? Do you think this is a positive or negative situation? Nowadays, many people tend to have their home rather than hiring one in different countries. Various reasons can be included to in this debate. I profoundly believe that it is a positive development. There are several reasons why owing a home rather renting one plays a prominent role in people’s decision. Firstly, many people who do not have not their own home find it difficult to move to some another accommodation on a yearly basis. Since occupants may undergo exorbitant prices of real estate services as well as rental, people prefer to purchase an appropriate home rather than paying costly expenditures. Moreover, possessing a home has been regarded as a valuable wealth among people so that it is a feasible means to invest in buying their home in order to achieve benefits/profit, and they measure success by the material things possessions they own. This trend has a positive impact on people’s life. People who have not their own home are more likely to feel like homeless as well as lack of sense of belongs belonging, so they can easily loss lose their confidence , and they may face several problemssuch as emotional or social. Besides, young people know that owing a home is a prerequisite factor to in starting a family, so it is an appositive way to fight for their future in order to achieve this gold. In addition, people have to pay taxes for their buying a home, with the governments allocating more budget as a loan or contribution assistance in order to facilitate purchasing a house. In conclusion, there are several reasons why many people, in some countries, tend to have their own home rather than renting because of status position and difficulties of moving. From a long-term perspective, this trend brings about various benefits for people. Farnaz, Bozorgi ,AC module

In this work, we aim at solving the barrier-based safety problem for a potentially unknown stochastic dynamics through finite data collected from trajectories of the system ; and providing a lower bound on the safety of the system accompanied by an a priori confidence. To do so, in the first step/initially, we reformulate the barrier-based safety problem as a robust convex problem (RCP) and then we stick to the scenario-driven approach to tackle this problem. We take samples from the system and construct a scenario convex problem (SCP) and then webefore establishing a connection between the optimal solution of the obtained SCP and safety of the stochastic system. There are two sources of uncertainty, ; one comes from data and another the other one is caused by the stochasticity in the system. We incorporate the effect of both of them in our provided confidence. In continuesubsequently, the proposed approach is extended for a class of non-convex safety problems. Finally, we provide an algorithm in order to synthesize a safety-guided controller based on collected data. We conclude bring the paper to the end with two case studies to elucidate the effectiveness of our approach in practice.
