Question
In recent years, economists around the world have created new tools that quantify the overall well-being of a country’s citizens. Economists in India, for example, use an Ease of Living Index. This tool ______ economic potential, sustainability, and citizens’ quality of life.
Which choice completes the text so that it conforms to the conventions of Standard English?
A. measures
B. had measured
C. would have measured
D. will have been measuring
▶️Answer/Explanation
Ans. A
Correct Answer: A
Rationale
Choice A is the best answer. The previous sentence tells us how economists in India “use” a certain tool, while this sentence describes general facts about that tool. To express general facts (and also to match the simple present tense of “use”), we should use the simple present tense form “measures.”
Choice B is incorrect. This choice uses the past perfect tense, but the previous sentence tells us that the tool is currently used to measure things, so the past tense doesn’t make sense for this verb. Choice C is incorrect. This choice uses the future perfect conditional tense, but the previous sentence tells us that the tool is currently used to measure things, so the future tense doesn’t make sense for this verb. Choice D is incorrect. This choice uses the future perfect continuous tense, but the previous sentence tells us that the tool is currently used to measure things, so the future tense doesn’t make sense for this verb.
Question
Mathematician and meteorologist Edward Lorenz used the metaphor of the “butterfly effect” to explain how seemingly minor events can have major impacts on future weather. According to Lorenz’s metaphor, the wind from a butterfly flapping ______ in Brazil might eventually grow into a storm elsewhere across the globe.
Which choice completes the text so that it conforms to the conventions of Standard English?
A. its wings
B. its wings’
C. it’s wing’s
D. it’s wings’
▶️Answer/Explanation
Ans. A
Correct Answer: A
Rationale
Choice A is the best answer. The conventions being tested are the use of possessive determiners and plural nouns. The singular possessive determiner “its” and the plural noun “wings” correctly indicate that the butterfly has multiple wings.
Choice B is incorrect because the context requires the plural noun “wings,” not the plural possessive noun “wings’.” Choice C is incorrect because the context requires the singular possessive determiner “its” and the plural noun “wings,” not the contraction “it’s” and the singular possessive noun “wing’s.” Choice D is incorrect because the context requires the singular possessive determiner “its” and the plural noun “wings,” not the contraction “it’s” and the plural possessive noun “wings’.”
