题目：

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.
Which of the following is an assumption on which the argument depends?

选项:

A、Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.
B、In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
C、Equipping a radio station with RDS technology does not decrease the station's listening area.
D、In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.
E、The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

题目：

Jennifer:  Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.  The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.
 
Brad:  There must be another explanation:  as you yourself said, the decline was on the order of 10,000 rentals.  Yet Videorama sold only 4,000 videos in 1994.
 
Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?

选项:

A、In 1994 Videorama rented out more videos than it sold.
B、In 1994 two new outlets that rent but that do not sell videos opened in Centerville.
C、Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.
D、People often buy videos of movies that they have previously seen in a theater.
E、People who own videos frequently loan them to their friends.

Scientists have modified feed corn genetically, increasing its resistance to insect pests. Farmers who tried out the genetically modified corn last season applied less insecticide to their corn fields and still got yields comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less, and what these farmers saved on insecticide rarely exceeded their extra costs for seed. Therefore, for most feed-corn farmers, switching to genetically modified seed would be unlikely to increase profits.

Which of the following would it be most useful to know in order to evaluate the argument?
没有理解为什么D是对的，需要比较的不是普通种子需要的杀虫剂用量吗？为啥转基因corn的杀虫剂用量可以影响结论？

Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.

Which of the following, if true, most strengthens the argument?
可以理解为什么C对，但是为什么E的slight decline是影响很小到可以忽略不计呢？就是小规模的食物减少也会引起seal减少，从而使orca吃otter

When there is less rainfall than normal, the water level of Australian rivers falls and the rivers flow more slowly. Because algae whose habitat is river water grow best in slow-moving water, the amount of algae per unit of water generally increases when there has been little rain. By contrast, however, following a period of extreme drought, algae levels are low even in very slow-moving river water.

Which of the following, if true, does most to explain the contrast described above?
