●Question 2. Critical Reasoning
When a new restaurant, Martin’s Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville’s only other restaurant, would suffer from the competition. Surprisingly, however, in the year since Martin’s Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.
Which of the following, if true, most helps to explain the increase?
A. Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays.
B. Most of the customers of Martin’s Cafe had never dined in Riverville before this restaurant opened, and on most days Martin’s Cafe attracts more customers than it can seat.
C. The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn.
D. The Wildflower Inn is not open on Sundays, and therefore Riverville residents who choose to dine out on that day must either eat at Martin’s Cafe or go to neighboring towns to eat.
E. A significant proportion of the staff at Martin’s Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin’s Cafe.

●Question 4. Problem Solving
At a garage sale, all of the prices of the items sold were different. If the price of a radio sold at the garage sale was both the 15th highest price and the 20th lowest price among the prices of the items sold, how many items were sold at the garage sale?
A. 33 B. 34 C. 35 D. 36 E. 37
●Answer to Q1: D
In A and E, the pronoun ‘it’ should be ‘they’ or ‘them’ to refer to ‘saffron threads’. And the subject ‘saffron threads’ in B can’t be the agent of the preceding expression ‘to extract’. In C, ‘soaking them’ should be changed into ‘to soak’ in terms of the idiom related to the noun ‘way’. So, the answer is D.
●Answer to Q2: B
The prediction that the opening of Martin’s Cafe;, a new restaurant in Riverville, will lead to severe competition between Martin’s Cafe; and the Wildflower Inn, Riverville’s only other restaurant, depends on the assumption that there are a limited number of customers who can use both restaurants. In this context, only B is mentioning the customers who can accommodate the increase of the number of overall customers for both the Martin’s Cafe; and the Wildflower Inn. Therefore, the answer is B.
●Answer to Q3: E
(1) & (2) m=2, n=1, yes. But m=-2, n=-1, no, NOT sufficient, therefore the best answer is E.
●Answer to Q4: B
20+15=35, 35-1=34 since the radio is duplicated in the items, therefore the best answer is B
