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".
Hope that helped
Answer:
Laura Bush was an active first lady: She advocated for women’s health and promoted education.
Explanation:
<em>Laura Bush was an active first lady: She advocated for women’s health and promoted education </em>is an example of the use of a colon instead of a semicolon between independent clauses. The second sentence explains, illustrates, paraphrases, or expands information given in the first sentence. There is no definite agreement as to whether or not the first word of the second sentence should be capitalized. Usually, if the information in the second sentence is closely related to information from the first, the capital is not used. If the second sentence is a general or formal statement, many writers and editors decide to capitalize the first word. In the given example, the writer decided to capitalize the word <em>she,</em> although others may have done the opposite.
