Interrogative Sentences: 5 Types Tested in AMCAT Verbal

Verbal-ability rounds in AMCAT, CoCubes, and eLitmus test interrogative sentences in three ways: identify the type, find the grammatical error, or rewrite a statement as a question.

Getting any one of these wrong costs marks that tip you out of the verbal-ability cutoff. This guide covers all five types with their exact grammatical structure, the errors examiners plant, and what the tests actually ask.

Why interrogatives show up in placement verbal tests

Employers who use AMCAT or CoCubes want candidates who can ask clear, precise questions in client-facing and team roles. The verbal section uses interrogatives as a proxy for grammatical precision.

The AMCAT verbal-ability section covers English usage, grammar, and comprehension. Interrogative-sentence questions appear as sentence correction items (one part of the sentence is wrong, pick the fix) and as transformation tasks (convert this statement to a question, or vice versa). A solid grip on the five types removes guesswork from both formats.

The five types of interrogative sentences

The Cambridge Grammar reference for English questions identifies five main interrogative structures. Each has a fixed pattern you can learn and apply mechanically.

Yes/No questions

Structure: Auxiliary + Subject + Main Verb + rest of sentence?

The auxiliary verb moves in front of the subject. The answer is yes or no.

• Q: Do you like ice cream?
• Q: Is she coming to the meeting?
• Q: Has he submitted the application?

Wh- questions

Structure: Wh-word + Auxiliary + Subject + Main Verb + rest of sentence?

The question word leads. The answer gives specific information, not just yes or no.

• Q: What is your branch of engineering?
• Q: Where do you want to be posted?
• Q: Why are the results delayed?

Choice questions

Structure: Auxiliary + Subject + Option A + or + Option B + ?

These present two (or more) options joined by “or”. The answer names one of the options.

• Q: Do you prefer morning or evening shifts?
• Q: Will you attend the drive on Monday or Tuesday?
• Q: Is the interview online or in person?

Tag questions

Structure: Statement, (auxiliary)(n't) + pronoun?

A tag question attaches a short question to the end of a statement to seek confirmation. Two rules apply together: the tag uses the same auxiliary verb as the statement, and the polarity flips. When the statement has no explicit auxiliary, English inserts ‘do’, ‘does’, or ‘did’ in the tag: ‘She studies every day, doesn’t she?’

• Positive statement, negative tag: “She is a doctor, isn’t she?”
• Negative statement, positive tag: “They haven’t arrived, have they?”
• “You like the plan, don’t you?”

Indirect questions

Structure: Reporting phrase + if/whether/wh-word + Subject + Verb + rest of sentence

Indirect questions embed a question inside a polite request or a statement. The key difference from direct questions: no inversion in the embedded clause. The word order reverts to normal statement order.

• “Could you tell me where the bank is?” (not: where is the bank)
• “Do you know what time the train leaves?”
• “I wonder whether she will join us.”

Interrogative words: pronouns, adverbs, and adjectives

The wh- word family appears across grammar tests in three grammatical roles. Knowing the role tells you whether the word needs a noun after it.

Interrogative pronouns

These stand alone and replace an unknown noun:

• Who called you? (subject position)
• Whom did you contact? (object position)
• What is your CGPA?
• Which of these options is correct?
• Whose bag is this?

Interrogative adverbs

These modify verbs and ask about time, place, reason, or manner:

• When will the results be announced? (time)
• Where is the test centre? (place)
• Why was the shortlist delayed? (reason)
• How do you approach aptitude problems? (manner)

Interrogative adjectives

These come directly before a noun and describe it:

• Which college did you attend?
• What score do you need to clear the cutoff?
• Whose report is due today?

The words “which”, “what”, and “whose” appear in all three roles. The position decides the role: standing alone makes it a pronoun or adverb; coming before a noun makes it an adjective.

Four common errors placement tests plant

Examiners repeat these four error types. Recognising the pattern earns the point without re-reading the full sentence.

Error 1: Wrong word order in wh- questions

• Incorrect: “Where you are going?”
• Correct: “Where are you going?”

The auxiliary must come before the subject. Students who directly translate from a regional language often produce this error.

Error 2: Missing auxiliary verb

• Incorrect: “You going to the campus drive?”
• Correct: “Are you going to the campus drive?”

Yes/No questions always need an auxiliary. Without it, the sentence reads as a fragment or a statement, not a question.

Error 3: Wrong tag polarity

• Incorrect: “She is a good student, is she?”
• Correct: “She is a good student, isn’t she?”

A positive statement takes a negative tag. Writing a positive tag after a positive statement is the single most-tested tag-question error in CoCubes verbal.

Error 4: Inversion inside indirect questions

• Incorrect: “Could you tell me where is the bank?”
• Correct: “Could you tell me where the bank is?”

Once a question is embedded inside a reporting clause, the word order reverts to normal statement order. The inversion that works in a direct question breaks the grammar of an indirect one.

A quick check for any indirect question: read the embedded clause as a standalone statement. If it sounds grammatically complete, the word order is right. If it sounds inverted, fix it.

What placement tests actually ask

AMCAT verbal has three interrogative-question formats:

• Sentence correction: one underlined segment is wrong; pick the corrected version. The error is usually a missing auxiliary, wrong word order, or wrong tag polarity.
• Sentence transformation: rewrite the sentence as an indirect question, or convert a statement to a yes/no question. The transformation must preserve the meaning and follow the correct structure.
• Error identification: four numbered parts of a sentence; identify the part with a grammatical error. For interrogatives, check auxiliary position and tag polarity first.

The three formats test the same underlying grammar knowledge; only the question frame differs. CoCubes verbal follows a similar pattern. eLitmus uses reading-comprehension passages where interrogative sentences appear in context. You identify whether each sentence is a direct or indirect question, and whether the punctuation (question mark or full stop) matches the type.

The precision needed to distinguish a yes/no question from a wh- question is the same precision that separates a useful prompt from a vague one when working with LLMs. A yes/no question sends a model toward a binary answer; a wh- question opens up a detailed response. TinkerLLM puts real API calls in your hands for ₹299. The output difference between “Did the model understand?” versus “What did the model misunderstand?” is immediately visible in the response.
