Sat practice Test #8 Answer Explanations

Choice A is the best answer. No change needs to be made because 
the word “deformation” provides the most precise description of what 
results when fuel droplets lose their symmetrical form while burning. 
A droplet that is deformed loses some good attribute due to the 
influence of some external condition.
Choices B and D are incorrect because “alteration” and “modification” 
imply that something is changed on purpose. Choice C is incorrect 
because “transformation” means that one thing is changed into 
another. None of these choices is accurate when discussing the effect 
of “gravitational influence” and the “movement of molecules” on 
droplets of fuel.
QUESTION 37
Choice B is the best answer. The plural verbs “cause” and “limit” 
agree in number with the plural pronoun “both,” which refers to the 
plural noun “variations.”
Choices A and C are incorrect because “causes” and “limits” are 
singular verbs that don’t agree in number with the plural pronoun 
“both.” Choice D is incorrect because “has caused” and “has limited” 
are also singular verbs. Additionally, they are present perfect tense 
verbs that are used to describe a past event that has an influence on 
the present, which is not the case in this context.
QUESTION 38
Choice D is the best answer. The underlined portion should be deleted 
because “built for this purpose” repeats the idea of being “specially 
designed” used previously in the sentence.
Choices A, B, and C are incorrect because they are redundant. There is 
no reason to repeat the idea of “specially designed.”
