CR 1 Since the introduction of low-cost airlines, delays at the nation's busiest airports have increased by 50 percent. To combat this problem, takeoff and landing slots at the busiest airports must be re-allocated with a significant preference towards traditional airlines, or those not considered low-cost airlines, over low-cost airlines.
If true, each of the following casts doubt on the effectiveness of the solution proposed above EXCEPT
A. The primary cause of delays at the nation's busiest airports is weather-related.
B. The delays caused by traditional airlines have continually increased, while those caused by low-cost airlines have continually decreased since the introduction of low-cost airlines.
C. Low-cost airlines account for a higher proportion of the delays than do non-low-cost airlines.
D Traditional airlines already account for approximately ninety percent of all takeoff and landing slots at the nation's busiest airports, as low-cost airlines tend to fly into and out of less busy airports.
E. Low-cost airlines, on average, account for a much lower proportion of the delays than do non-low-cost airlines.

CR 2 The use of Deprogan, a chemical produced by Swift-Besco Corporation, has been banned in Swift-Besco’s home country because it can cause health issues. So, Swift-Besco sells Deprogan only in other countries. However, Deprogan returns from countries in which it is used to Swift-Besco’s home country via global flows of air and water. Clearly, by selling Deprogan in other countries, Swift-Besco is increasing health risks to people in its home country.
Which of the following, if true, provides the most additional support for the claim made?
(A) Deprogan enters air and water because of lax practices in the countries in which it is sold.
(B) Swift-Besco produces two chemicals that can cause health issues the use of which has not been banned in its home country.
(C) Employees of Swift-Besco involved in the production of Deprogan must follow strict procedures in order to ensure that they are not harmed by this chemical.
(D) Because of patent laws, no company other than Swift-Besco produces and sells Deprogan.
(E) Many countries in addition to Swift-Besco’s home country have banned Deprogan.
