So the verb is "to use" and the tense is the past conditional. This is indicated by the words, "has been". Like, "I have used," or something similar.
The word "had" or "have" is almost always indicative of either the past perfect or past conditional.
The opposite of that is the past, or preterite tense, as in it definitely happened, as in, "I used it".

Explanation:.
Answer:
<em>"Similar."</em>
Explanation:
In the given passage, a cup of strong and weak coffee is compared based on their effect and caffeine content. And in the two sentences, even though it is a comparison transition between a strong and weak coffee, the transition word used is "similar".
In both the sentences, the physical effects of coffee are compared, with the same result- <em>"80 milligrams of caffeine or enough to boost a heart rate and blood pressure." </em>This means that both a weak and strong cup of coffee have the same physical impact on a person.
Thus, the comparison transition used is "similar".
