Explanation We’ll go for PRECISE because there is a simple grammatical rule we can use.The subject of the sentence is chia seeds, which is plural, so the verb must match it—contain, not contains. Of the three answers in which the verb matches the subject, two have other mistakes: (B) uses less, a quantifier used for uncountable nouns, to describe a countable noun—acids, and (D) makes an illogical comparison, which suggests that chia seeds contain hemp seeds. The answer is therefore (C).
We’ll go for LOGICAL because we can correct the wrong illogical comparison.The construction of the comparison made in the original sentence makes it sound as if chia seeds contain hemp seeds (because it says fewer acids than hemp seeds), but one kind of seed cannot contain another kind. Answer choices (D) and (E) make the same faulty comparison. Answer choice (B) gets the comparison (... than those found in hemp seeds) right but contains a new mistake: it uses less, a quantifier used for non-count nouns, to describe the countable noun acids. The answer is therefore (C).
