Passage context: 'If it is improperly introduced into the environment, acid whey runoff CAN POLLUTE WATERWAYS, depleting the oxygen content of streams and rivers as it decomposes.' Which choice best replaces the underlined portion?
ANO CHANGE (can pollute waterways,)
Bcan pollute waterway's,
Ccould have polluted waterways,
Dhas polluted waterway's,
Answer & Solution
Correct answer: A. NO CHANGE (can pollute waterways,)
Choice A is correct. 'Waterways' is a plural noun, not a possessive, so no apostrophe is needed. 'Can pollute' (present-tense modal) matches the sentence's hypothetical framing ('If it is improperly introduced').
