199. In a certain restaurant, if each soft drink costs the same amount, what is the cost, excluding sales tax, of 1 soft drink?

(2) The cost, including sales tax, of 3 soft drinks is \$4.05.

 (a) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. (b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. (c) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. (d) EACH statement ALONE is sufficient.

200. Mayor of Alberville: Factories in Alberville together emitted twenty percent less carbon dioxide in 2001 than in 2000. The decline in emissions was probably due almost exclusively to the March 2001 development of floating seaweed farms, the first step toward reducing carbon dioxide emissions that, in addition to being cost-efficient, was also widespread.

Scientists: That cannot be the cause. As you yourself clearly stated, carbon dioxide emissions were reduced by twenty percent. Yet seaweed farms can only absorb ten percent of Alberville factories' emissions.

Which of the following, if true, would most seriously weaken the force of the objection that the scientists present to the mayor's explanation?

 (a) The cost of the seaweed farms was covered by a tax increase to industrial firms in Alberville. (b) The number of factories in Alberville was greater in 2001 than in 2000. (c) Seaweed farms had a greater effect on Alberville emissions levels than any other plan undertaken in Alberville. (d) When seaweed plants die, they can be used as a low-emissions fuel source.
