SAT Practice Test #8
Choice A is incorrect because the initial parenthesis is missing and
no comma is needed between the noun “quantities” and the modifying
information. Choice C is incorrect because
the initial parenthesis is
missing. Choice D is incorrect because no semicolon is needed before
the parenthetical information.
QUESTION 5
Choice D is the best answer. According to the information from the graph,
33 million tons of food waste were discarded in US landfills in 2009,
which is consistent with the discussion of food waste in the passage.
Choices A, B, and C are incorrect because
the passage thus far has
focused on compost. Metal, rubber, leather, and textiles are not
materials that are composted.
QUESTION 6
Choice C is the best answer. According to the graph, this is the only
choice that makes the sentence true. More
food waste was discarded in
landfills in 2009 “than any other substance, including plastics or paper.”
Choices A, B, and D are incorrect because they are not true, according
to the graph. The graph
indicates that less glass, metal, and yard waste
were discarded in the landfills than plastics and paper.
QUESTION 7
Choice B is the best answer. No comma is needed between the
comparative adjective “worse” and the comparative conjunction “than.”
Choices A, C, and D are incorrect because the word “then” indicates
“when” and is not used in comparisons (choices A and C), and no
comma is needed after worse (choice D).
QUESTION 8
Choice C is the best answer. The present tense singular verb “contributes”
agrees in number with the singular noun “material,”
and the present tense
verb is consistent with the other present tense verbs in the passage.
Choices A and B are incorrect because “contribute” (choice A) and “are
contributing” (choice B) are plural present tense verbs. Choice D is
incorrect because “have contributed” is a plural past tense verb.
