Topic: Conjugation of Verb,

Best Answer Explained in Below-:

The correct choice for the blank in the sentence "It was our policy to deal with the problems as they-” is A) "arose." This usage is rooted in the proper application of the verb forms related to emergence or occurrence.

The verb "arise" means to come into being, to emerge, or to occur. When we say problems "arose," we are indicating that they emerged or came to our attention. This is the appropriate context for the sentence, which discusses a policy of dealing with problems as they occur.

On the other hand, the other options do not fit the context correctly:

B) "rose" is the past tense of "rise," which generally refers to moving upward or increasing; it does not convey the emergence of problems.

C) "raised" is the past tense of "raise," meaning to lift or elevate something, and it does not apply to problems that come up.

D) "roused" means to awaken or provoke, typically in a context of stirring emotions or actions, which again does not fit the emergence of problems.

Therefore, "arose" is the only word that correctly conveys the intended meaning of dealing with problems as they come up.
