Answer:
3.The defense lawyer concluded his remarks with a foolproof argument of the defendant's innocence.
Explanation:
Sentence number 3 is the one that uses the word foolproof as described by the second definition because it is stating that there is not any possibility to fail with this argument. In other words, it is saying that with that argument, the layer is going to win the case.
The other options use the term foolproof as something that is designed to function despite the human error, they all refer to an object or activity that involves human beings, and that did or did not work despite human error
Taking the meaning of the words into consideration, the best way to complete the sentence is the following:
Her ivory brow furrows in delicate lines (option A).
<h3>What is the meaning of furrow?</h3>
The original meaning of the verb "to furrow" is to make a a line on the surface of something. That may seem strange, but this verb is often used with the word "brow".
It is common to say that someone has a furrowed brow. That means lines have appeared above that person's eyes, usually indicating they are concentrating or deep in thought.
With that in mind, we can choose letter A to complete the sentence: Her ivory brow furrows in delicate lines.
