Q1. In the years 1971 to 1980, the population of the state prison system was on average about 82 percent of maximum occupancy. During those years, the average number of prisoners entering the system each year was equivalent to 9.1 percent of maximum occupancy. From the years 1981 to 1984, the average number of prisoners entering the system each year fell to 7.3 percent of maximum occupancy, yet the population of the state prison system rose to almost 89 percent of maximum occupancy. Which of the following, if true, helps to resolve the apparent discrepancy? (A) The average sentence of a prisoner in the state system increased from 1981 to 1984. (B) Beginning in 1981, many of those entering the state prison system had been transferred from prisons in other states. (C) Between 1981 and 1984, the percentage of prisoners incarcerated for violent crimes increased by 26 percent. (D) In 1981, a legislative fact-finding committee proposed a revision of the state’s parole and work release programs. (E) Between 1971 and 1984, the proportion of active criminals actually caught and incarcerated in the state prison system has steadily increased.

Q2. Twenty years ago, in order to rid Katarina Island of the menace of an insect larva X that was destroying rice crops, a special caterpillar-eating bird Y was introduced to the island. Now, however, overconsumption of fruits by the enormous Y population menaces many of the island’s fauna. Agriculturists plan to reduce Y’s population by using a chemical spray, which has caused devastating epidemics in Y’s population. However, there is a small chance of this chemical infecting the native Katarinian grey hornbill, an endangered fruit-eating bird. The agriculturists’ plan, therefore, is protective of agricultural interests in terms of controlling fruit consumption on the one hand but will increase the danger to native bird populations on the other. The argument above assumes which of the following? A. It is possible to reduce Y’s population without causing any danger to the Katarinian grey hornbill. B. None of the birds or animals in Katarina prey on the bird Y. C. In places where the chemical was used, the populations of bird Y were successfully controlled. D. The use of the chemical can be controlled in a manner that will not completely wipe out the bird Y population on the island. E. The enormous Y population is not a bigger threat to the Katarinian grey hornbill than the chemical spray. Difficulty - Hard
CR Questions June - 25 :Q1. ShopEasy, a grocery delivery company, has developed a new mobile app to streamline the ordering process for customers and reduce delivery times. The company’s management argues that by launching an ambitious worldwide marketing campaign, the mobile app will quickly gain immense popularity and, consequently, ShopEasy will become the preferred grocery delivery service for at least 50% of potential customers. Hence, the management believes that launching the worldwide marketing campaign is critical for the app’s success and ultimately, to gain a dominant position in the market.
Which of the following is an assumption on which the management’s conclusion is based?
(A) No other grocery delivery companies are in the process of improving their services or offering a superior mobile app.
(B) The majority of the potential customers have access to reliable information about the ShopEasy app and the potential benefits of using it.
(C) ShopEasy’s mobile app is the most innovative and user-friendly mobile app for grocery delivery services in the market.
(D) No significant technological, geographical, or financial barriers would prevent a substantial portion of potential customers from accessing, downloading, and using the ShopEasy app effectively.
(E) The market for grocery delivery services will not undergo a major transformation that would affect the need for or relevance of ShopEasy’s new mobile app.

Q2. In an attempt to address the growing concerns about water scarcity, a group of engineers has developed a new process for desalination that is significantly more energy-efficient than traditional methods. The engineers believe that by promoting this new technology as an alternative water source, countries experiencing severe water shortages will benefit from greater access to potable water without exacerbating their existing environmental issues.
Which of the following, if true, most strengthens the engineers’ argument?
(A) Even in regions where there is no apparent shortage of freshwater resources, people are becoming more conscious about sustainable consumption and waste reduction.
(B) Other technological innovations in agriculture and manufacturing decrease reliance on large quantities of freshwater without imposing prohibitive costs.
(C) If widely adopted worldwide, the new desalination method would not substantially increase local or global demand for energy resources or harm marine ecosystems due to its efficiency.
(D) Previous efforts to establish more efficient desalination processes have only seen limited success because most improvement attempts have been focused on marginal enhancements rather than disruptive technologies.
(E) Several other research teams around the world are independently working on similar approaches for advancing desalination systems inspired by natural filtration mechanisms.
