Verbs

Concept: This question tests subject-verb agreement, specifically with phrases like "one or the other." The verb must agree with the true subject of the sentence. Step 1: Identify the subject of the sentence The phrase "One or the other of those fellows" is the subject. When "one" is used in such a construction (e.g., "one of the boys," "one or the other"), the true subject is "one," which is singular. The phrase "of those fellows" is a prepositional phrase modifying "one or the other." Step 2: Determine the number of the subject Since "one" is singular, the subject "One or the other" is considered singular. Step 3: Choose the auxiliary verb that agrees with a singular subject in the present perfect tense The main verb is "stolen," which is the past participle of "steal." This indicates the sentence is likely in the perfect tense (e.g., present perfect or past perfect). The options provided suggest present perfect. The present perfect tense is formed with "has/have + past participle."
For singular subjects (he, she, it, one), use "has."
For plural subjects (they, we) and for "I" and "you," use "have." Since the subject "One or the other" is singular, the correct auxiliary verb is "has." Step 4: Evaluating the options
(1) has: Correct. "One or the other ... has stolen the car." (Present Perfect tense, active voice)
(2) have: Incorrect. "have" is used with plural subjects.
(3) has been: This would form "has been stolen." If the car "has been stolen" (by one of them), the sentence structure would be different (passive voice: "The car has been stolen by one or the other..."). Here, "one or the other" is performing the action (active voice).
(4) have been: Incorrect, plural and also suggests passive voice in this context. The sentence is in the active voice: one of the fellows performed the action of stealing.

Step 1: Identify the subject of the sentence.
The subject of the sentence is "Ansha". Step 2: Determine the number and person of the subject.
"Ansha" is a singular noun, referring to a third person (he/she/it). Step 3: Apply the rules of subject-verb agreement for the simple present tense.
In the simple present tense, for a third-person singular subject (he, she, it), the verb typically takes an "-s" or "-es" ending. Step 4: Evaluate the given verb options.

(1) want: This form is used with plural subjects (we, you, they) or the first-person singular (I).
(2) wants: This form is correctly used with a third-person singular subject like "Ansha" in the simple present tense.
(3) wanting: This is a present participle and would typically be used with a form of "to be" (e.g., "Ansha is wanting"), or as an adjective/noun. It is not a standalone verb in this context.
(4) become: While "become" is a verb, it doesn't fit the context of wanting to be something. "Ansha wants to become a space scientist" would be grammatically correct if "wants" were followed by "to become," but "become" alone doesn't convey the same meaning as "wants to be." The sentence structure "Ansha [...] to be" specifically calls for a verb that completes the desire or intention. Step 5: Conclude the correct verb form.
"Wants" is the correct form of the verb for the singular third-person subject "Ansha" in the simple present tense. (2) wants

Step 1: Understand the Context.
The sentence states that Mohan performed an action "yesterday," which indicates a past event. Therefore, the verb must be in the past tense to correctly describe the action that occurred in the past. Step 2: Analyze Each Option.
Option (1): buy — Incorrect, as "buy" is the base form of the verb and does not indicate past tense.
Option (2): bought — Correct, as "bought" is the past tense of "buy," which matches the context of the sentence.
Option (3): will buy — Incorrect, as "will buy" indicates future tense, not past tense.
Option (4): buying — Incorrect, as "buying" is the present participle form and does not indicate past tense. Step 3: Final Answer. $ $

Step 1: Identify the subject of the sentence.
The subject of the sentence is "Her hair". Step 2: Determine the grammatical number of the subject.
In English, the word "hair" is generally treated as an uncountable noun and takes a singular verb, even when referring to multiple strands of hair. For example, "Her hair is long," not "Her hair are long." Step 3: Choose the verb form that agrees with the singular subject.
(1) are: Plural form of "to be". Incorrect.
(2) were: Plural past tense form of "to be". Incorrect.
(3) is: Singular present tense form of "to be". Correct.
(4) am: First person singular form of "to be". Incorrect. Step 4: Complete the sentence with the correct verb. The correct sentence is: "Her hair is crisp and black." $ $
