Question

Identify the subject of the verb in the following sentence: 
Every boy along with his parents is waiting in the next room.

Accepted Answer

Here is a detailed explanation for the given question:

**Explanation:**

The question asks to identify the subject of the verb "is waiting" in the sentence: "Every boy along with his parents is waiting in the next room."

**Justification for Option 1: Every boy along with his parents (Correct)**

1.  **Identifying the Verb:** The verb in the sentence is "is waiting."
2.  **Identifying the Subject:** To find the subject, we ask "Who or what is waiting?" The answer is "Every boy along with his parents."
3.  **Head Noun and Agreement:** In this sentence, "Every boy" is the head noun of the subject. Phrases like "along with," "as well as," "in addition to," "together with," etc., are considered additive phrases, not conjunctions. They introduce additional information but do not change the number of the subject for verb agreement. The verb always agrees with the head noun that comes before these phrases. Since "Every boy" is singular, the verb "is waiting" (singular) is correctly used.
4.  **Complete Subject:** The complete subject includes the head noun ("Every boy") and all the words that modify it or are part of the subject phrase, which in this case extends to "along with his parents." Therefore, "Every boy along with his parents" functions as the complete subject of the verb.

**Why other options are incorrect:**

*   **Option 2: His parents (Incorrect)**
    *   "His parents" is part of the prepositional phrase "along with his parents." In this construction, "parents" is the object of the preposition "with," not the subject of the main verb.
    *   If "His parents" were the subject, the verb would need to be plural ("are waiting"), but the sentence uses the singular verb "is waiting," which agrees with "Every boy."

*   **Option 3: Boy along with (Incorrect)**
    *   This option is incomplete. While "boy" is the core noun that the verb agrees with, "Every" is a crucial determiner that modifies "boy" and is part of the subject phrase.
    *   "along with" is a prepositional phrase connector and cannot stand alone as the subject or part of an incomplete subject phrase in this manner.

*   **Option 4: Every (Incorrect)**
    *   "Every" is a determiner or an adjective that modifies the noun "boy." It cannot function as the subject on its own. The subject must be a noun, pronoun, or a noun phrase.
