Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

The sentence in question uses the phrase "Each and every student and instructor," which signifies that we are referring to individual members of a collective group. In English grammar, when "each" is the subject of a sentence, it takes a singular verb form because it emphasizes individual units rather than the group as a whole. Therefore, the verb that follows must agree in singular form.

Among the options provided, the correct choice is **B) hopes.** Here’s why:

- **A) hope** is incorrect because it is the plural form, which does not agree with the singular subject.
- **C) hoped** implies a past action and is not suitable since the sentence discusses a future expectation.
- **D) has hoped** suggests a present perfect tense, which is also inappropriate as it again does not align with the future context of the sentence.

In contrast, "hopes" correctly maintains singular agreement with "each," indicating that each individual—whether a student or instructor—holds a personal expectation for a new facility by next year. Thus, the proper construction is “Each and every student and instructor in this building hopes for a new facility by next year.”
