The supply of tablets (is, are) low.

he who...

(he should go, not him should go)

The supply is low

The correct answer for the first sentence is "he who should go." To understand why, we can break down the sentence and consider the grammar rules around subjective and objective pronouns.

In the sentence, "We thought it was ________ should go," we are choosing the correct pronoun to fill in the blank. The pronoun should refer to a person, as indicated by the options "he" and "him." To determine the correct pronoun, we need to consider the role it plays in the sentence.

The pronoun in question is the subject of the verb "should go." The subject of a sentence is typically represented by subjective pronouns, such as "he" or "she." In this case, we want to choose the pronoun "he."

Therefore, the correct answer is "he who should go."

Moving on to the second sentence, "The supply of tablets (is, are) low," we are asked to choose between the verb forms "is" or "are."

To determine the correct verb form, we need to consider the subject of the sentence, which is "The supply of tablets."

In this case, "the supply" is a singular noun, so we should use the singular verb form "is." Therefore, the correct answer is "The supply of tablets is low."
