Answer:
The correct sentence is:
3. He tried to affect our vote.
Explanation:
The sentences we are analyzing here are testing our knowledge of words that sound similar but have different meanings, or words that have close meanings with small differences.
For the first sentence, the verb should be "lay" instead of "lie". "Lie" is an intransitive verb, which means it does not act upon an object. "Lay", however, needs an object. We lay something. The sentence should be: Please lay this book on the table.
The second sentence confuses "except" with "accept". Just keep in mind that "except" is related to "exception", which means to exclude something. The sentence should be: Please accept my apology.
The third sentence is correct. We must use "affect", which is a verb. Some people confuse it for "effect", which is a noun.
Finally, the fourth sentence uses "set" instead of "sit", but the two verbs have completely different meanings. From the context, we can tell "sit" is the best option. The person wants to sit down to rest.
