","stem_html":"Which choice completes the text so that it conforms to the conventions of Standard English?
","rationale_html":"Choice D is the best answer. The convention being tested is end-of-sentence punctuation. This choice correctly uses a question mark to punctuate the interrogative sentence “how are they able to move so fast?” The interrogative sentence asks a direct question, and the next sentence answers it.
Choice A is incorrect because the context requires an interrogative sentence. The exclamative sentence “how they are able to move so fast!” emphasizes the penguin’s high rate of speed, but it doesn’t set up the next sentence’s explanation of how the penguins achieve such speeds. Choice B is incorrect because a period can’t be used in this way to punctuate an interrogative sentence. Choice C is incorrect because the context requires an interrogative sentence. The exclamative sentence “how they are able to move so fast” emphasizes the penguin’s high rate of speed, but it doesn’t set up the next sentence’s explanation of how the penguins achieve such speeds.\n
