Q1. In the last year, a company has lost a few clients and gained a few. But the number of clients lost has been lower than the number of new clients. Also, the average sales for each new client are more than the average sales for each of the other clients. Therefore, it is likely that the company’s average sales per client have been increasing steadily
Which of the following is required for the above argument to hold?
A. Currently, the total number of clients is more than the total number of clients that existed before the company lost some of its clients
B. The average sales for each new client are at least equal to the average sales for each other client
C. Most of the clients lost were already planning to terminate their relationship with the company
D. There has been no decrease in the quality of the services provided by the company since the company lost some of its clients last year
E. The average sales per client lost were not significantly higher than the average sales for each of the other clients

Q2. The industrial revolution, which took place during the late eighteenth century and the early nineteenth century, is the historical time period in which new manufacturing processes began to be used on a large scale. While some argue that the individual’s standard of living increased at an unprecedented rate during this time, others believe that it was only the overall growth of the economy that increased, and that standards of living did not rise significantly until the twentieth century; the latter belief is clearly true, since _________________________
Which of the following, if true, best completes the passage above?
A. social writings from this time indicate that workers’ living conditions deteriorated during the revolution.
B. the revolution affected not just the professional lives but also the everyday lives of people at the time.
C. new manufacturing processes led to marked improvements in the efficiency of the production process across various kinds of industries
D. classical economics does not even mention the possibility of sustained economic growth during the revolution
E. most economists now believe that socioeconomic changes during the revolution occurred as a rapid rather than gradual process
CR Butler Questions December - 8 :Q1. There is an increasing trend in opting for hybrid cars or cars that use rechargeable batteries to augment the gasoline engine. Car manufacturers claim that such cars drive longer per unit of gasoline since there is no gasoline used when the car is powered by batteries. In reality, these cars are powered by batteries only when the car is driving at low speeds and by gasoline engine otherwise. Therefore, in the region of Carmenia, hybrid cars provide little advantage over cars with comparable gasoline engines.
Which of the following if true strengthens author’s argument above
A. The speed breakers on the highways of Carmenia are smaller and lower in height than those on the highways of the neighbouring cities.
B. On an average, roads of Carmenia have significantly more speed breakers than the roads of any other city in the world
C. Hybrid cars typically extract slightly more energy from gasoline than regular cars do.
D. The Minimum Speed Limit in the nearby cities is well above the battery-operating range of a hybrid car
E. While travelling within Carmenia, the amount of gasoline consumed by a hybrid car is quite comparable to the amount of gasoline consumed by a conventional gasoline-engine driven car.
Q2. Children with photosensitive epilepsy, a condition in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights or regular moving patterns, are usually not allowed to use computers as the images on the screens are continually refreshed. These images can hence move or flicker, triggering a seizure. However, laboratory tests have shown that the eyes of such children adapt very well to using computers. Parents, therefore, can safely let such children use computers to do extensive research work for school projects, if not for playing games.
Which of the following, if true, weakens the conclusion drawn above?
A. Research typically requires the brain to use less energy to interpret visual stimuli than games do.
B. Parents of children with photosensitive epilepsy are unlikely to be aware of the latest findings made by scientists in the field.
C. Playing games is not as tiring a mental activity as doing research work on computers is.
D. Preliminary results have shown that the brain of such children cannot process constant inflow of images for long hours, and such an inflow could trigger a seizure.
E. Seizures can also be triggered by sources such as smart phones, televisions and game stations, which display moving or flickering images in much the same way as a computer does.
