Grammar Quiz # 4

Explanation
The correct answer is "who" because in this question, "who" is used as the subject of the verb "is calling." It is asking for the identity of the person who is calling.

Explanation
The correct answer is "an / a". The indefinite article "an" is used before words that begin with a vowel sound, while the indefinite article "a" is used before words that begin with a consonant sound. In this case, "history" begins with a consonant sound, so "a" is used. However, "hour" begins with a vowel sound, so "an" is used.

Explanation
The correct answer is "I" because it is the correct pronoun to use when referring to oneself as the subject of a sentence. In this case, Charles and I are both attending the conference.

Explanation
The correct answer is "on". In this sentence, "on" is used to indicate a specific occasion or event. It suggests that during that particular occasion, the person was not thinking well. The preposition "on" is commonly used to refer to specific dates, days, or occasions.

Explanation
The correct answer is "it is". In the sentence, "Microsoft announced," the subject is "Microsoft," which is singular. Therefore, the pronoun used to refer to Microsoft should also be singular, and "it is" is the correct choice.

Explanation
The correct answer is "fungi / potatoes". In this sentence, "fungi" is the plural form of "fungus" which refers to a type of organism, and "potatoes" refers to a type of vegetable. The sentence is stating that three fungi and two potatoes are needed for the soup.

Explanation
The word "who" is the correct answer because it is used to refer to a person. In this sentence, "The boy who threw the ball was blond," the relative pronoun "who" is used to introduce a clause that describes the boy. It indicates that the boy is the one who performed the action of throwing the ball and also provides additional information about the boy's hair color.

Explanation
The words "upon," "from," and "like" are all prepositions because they show a relationship between a noun or pronoun and another word in the sentence. However, the word "so" is not a preposition. It is commonly used as an adverb or a coordinating conjunction, but it does not function as a preposition.

Explanation
The subject "The other boys or Henry" is singular, so the correct verb form to use is "is."

Explanation
The correct answer is "me" because the phrase "just between you and me" is a common expression used to indicate confidentiality or secrecy. In this context, "me" is the correct pronoun to use as it functions as the object of the preposition "between." Using "myself," "I," or "mine" would be grammatically incorrect in this sentence.
