<p>Sugar-free candy, though not as healthy as fruit, are the snacks of choice for people on a diet.</p>
<p>Subject: Sugar-free candy (singular) Linking verb: are (plural)</p>
<p>Clearly, are has to be changed to is. </p>
<p>But what about "snacks of choice"? Isn't that also incorrect - "snacks of choice" is plural, and it refers to "sugar-free candy," which is singular.</p>
<p>Are there really two errors in this sentence? Or am I just delusional?</p>
<p>sa0209: The answer is B (according to the book). Here’s the explanation:</p>
<p>Whenever you see a verb, check to see if it agrees with the subject. IN this case, the subject is sugar-free candy, which is singular, so the verb are should be is. (A) and (C) are idiomatically correct. (D) uses the correct preposition.</p>
<p>realityisadream: I agree, “snacks of choice” doesn’t make any sense. It really seems as if both B and C are incorrect in this sentence.</p>
<p>Since candy is singular, are must be is and snacks must be snack. As IceQube pointed out, the singularity of diet is justifiable from the perspective that multiple people may share a diet; since we are to give the benefit of the doubt to sentences as they are written, then, on a diet is not an error but is nonetheless characteristic of bad question writing.</p>
<p>So the sentence contains two errors, making it problematic.</p>
