Yes No Question PatternsQuestion 1 of 10

Read this short exchange: A: 「このケーキはおいしくないですか。」 B: 「いいえ、おいしいです。」

Speaker B's response 「いいえ、おいしいです。」 to the negative question seems counterintuitive to many English speakers. Which explanation correctly interprets B's response?

「いいえ」 here is equivalent to English 'No' and confirms the cake is not delicious, making 「おいしいです」 a contradictory error that a native speaker would not produce.
「いいえ」 here agrees with A's negative premise, meaning 'No, it is not delicious,' but the following 「おいしいです」 is a polite correction showing B changed their mind mid-sentence.
「いいえ、おいしいです。」 is grammatically incorrect because when answering a negative question affirmatively in Japanese, the speaker must use 「はい」 followed by the negative form to avoid confusion.
「いいえ」 here contradicts A's negative premise, meaning 'No (your assumption is wrong), it is delicious.' Japanese yes/no responses align with the truth of the statement that follows, not with the surface form of the question.

Question 1

Read this short exchange: A: 「このケーキはおいしくないですか。」 B: 「いいえ、おいしいです。」

Speaker B's response 「いいえ、おいしいです。」 to the negative question seems counterintuitive to many English speakers. Which explanation correctly interprets B's response?

  1. 「いいえ」 here is equivalent to English 'No' and confirms the cake is not delicious, making 「おいしいです」 a contradictory error that a native speaker would not produce.
  2. 「いいえ」 here agrees with A's negative premise, meaning 'No, it is not delicious,' but the following 「おいしいです」 is a polite correction showing B changed their mind mid-sentence.
  3. 「いいえ、おいしいです。」 is grammatically incorrect because when answering a negative question affirmatively in Japanese, the speaker must use 「はい」 followed by the negative form to avoid confusion.
  4. 「いいえ」 here contradicts A's negative premise, meaning 'No (your assumption is wrong), it is delicious.' Japanese yes/no responses align with the truth of the statement that follows, not with the surface form of the question. (correct answer)
Explanation: When answering yes/no questions in Japanese, you must forget how English works. In English, "yes" and "no" respond to the surface form of the question. In Japanese, 「はい」 and 「いいえ」 respond to the truth of reality — specifically, whether the statement that follows is correct or incorrect. This distinction is exactly what this question tests. In the exchange, A asks 「このケーキはおいしくないですか」 — "Isn't this cake delicious?" — embedding a negative assumption. B responds 「いいえ、おいしいです」, which means "No (your negative assumption is wrong) — it IS delicious." The 「いいえ」 contradicts A's premise, and 「おいしいです」 confirms the truth. This is D, and it's the only logically and grammatically coherent reading. Choice A incorrectly maps Japanese 「いいえ」 onto English "No," treating it as confirmation that the cake is not delicious — exactly the English-speaker trap this question is designed to catch. Choice B invents a fictional "mid-sentence correction" that has no grammatical basis in Japanese; 「いいえ」 and 「おいしいです」 are perfectly consistent here, not contradictory. Choice C is simply false — there is no rule requiring 「はい」 followed by a negative form when answering affirmatively; that would actually create confusion, not resolve it. A reliable study tip: whenever you see a negative question in Japanese, ask yourself what the speaker is actually claiming to be true, then decide whether 「はい」 (yes, that's right) or 「いいえ」 (no, that's wrong) fits. Anchor your response to reality, not the question's grammatical polarity.

Question 2

Kenji is at a restaurant. The waiter asks: 「おすしはお好きですか。」 Kenji wants to answer that he does NOT like sushi. He is unsure whether to say 「はい」 or 「いいえ」 first.

Which response by Kenji is grammatically correct AND semantically clear in communicating that he does not like sushi?

  1. 「はい、すしはあまり好きではありません。」 — 「はい」 is required in Japanese whenever the speaker's response sentence contains a negative predicate, regardless of whether the original question was affirmative or negative.
  2. 「いいえ、すしはあまり好きではありません。」 — 「いいえ」 negates the affirmative premise of the question, and the predicate clearly states the negative, making the full response both grammatically correct and semantically unambiguous. (correct answer)
  3. 「いいえ、すしはあまり好きです。」 — 「いいえ」 signals the speaker's hesitation, and using 「あまり好きです」 with the affirmative form politely softens the expression of dislike without being overly direct or rude.
  4. 「はい、すしは好きではありません。」 — 「はい」 serves as a polite acknowledgment of the waiter's question, and the negative predicate that follows conveys the true meaning, so native speakers would find this combination natural and clear.
Explanation: When answering yes/no questions in Japanese, your choice of 「はい」or「いいえ」must align with whether you're confirming or denying the premise of the question — not simply whether your following sentence is positive or negative. The waiter's question 「おすしはお好きですか」 presents an affirmative premise: "Do you like sushi?" If Kenji does not like sushi, he is disagreeing with that premise, so he must open with 「いいえ」. B is correct because 「いいえ」properly signals disagreement with the affirmative question, and 「すしはあまり好きではありません」clearly and grammatically states the negative. The adverb 「あまり」paired with a negative predicate ("not that much") is a natural, polite way to express dislike in Japanese. Everything is consistent and unambiguous. A is wrong because it claims 「はい」is required whenever a negative predicate follows — this is a false rule. Using 「はい」before a denial of the question's premise contradicts the premise itself, creating confusion for the listener. C fails on two levels: while 「あまり」can soften a statement, it must pair with a negative predicate (「好きではありません」) to mean "don't like very much." Using 「あまり好きです」with an affirmative predicate is grammatically incorrect and means nearly the opposite of the intended message. D repeats A's error — using 「はい」as a polite filler before contradicting the premise is not a recognized pattern in standard Japanese and would genuinely confuse native speakers. Study tip: In Japanese, always match 「はい／いいえ」to the question's premise, not to the grammar of your own reply sentence.

Question 3

A learner wants to ask their teacher 'Are you a Japanese person?' politely. They produce: 「せんせいは日本人ですか。」 Their classmate suggests changing it to 「せんせいは日本人でしょうか。」 What is the functional difference between these two forms?

  1. 「でしょうか」 transforms the yes/no question into a rhetorical one, implying the speaker already suspects the answer, whereas 「ですか」 is reserved for situations where the speaker is genuinely uncertain about the information.
  2. 「ですか」 and 「でしょうか」 are interchangeable yes/no question forms with no meaningful difference in politeness, register, or nuance; the classmate's suggestion is unnecessary and does not improve the original sentence.
  3. 「でしょうか」 changes the sentence into an indirect embedded question that cannot receive a direct yes/no answer, making it unsuitable when the speaker is asking for straightforward factual information about a person.
  4. 「ですか」 is a direct yes/no question seeking a definite answer, while 「でしょうか」 is a softer, more tentative yes/no question that sounds more polite and less presumptuous, often used when speaking to superiors or in formal situations. (correct answer)
Explanation: When studying Japanese politeness and sentence-ending forms, pay attention to how small grammatical changes shift the tone and social register of a sentence, not just its basic meaning. 「ですか」 is a straightforward, direct yes/no question. It's polite, but it asserts a certain confidence — you're asking for a definite answer. 「でしょうか」, by contrast, adds the volitional/speculative auxiliary 「でしょう」before 「か」, which softens the question considerably. The speaker signals tentativeness, as if saying "I wonder if perhaps..." This makes the question sound less presumptuous and more deferential — exactly what you want when addressing a teacher or superior. So D correctly captures the functional difference: 「ですか」 is direct, while 「でしょうか」 is gentler and more formal. A is wrong because 「でしょうか」 is not rhetorical — it genuinely seeks an answer. Nor is 「ですか」 limited to situations of genuine uncertainty; it's simply the standard direct question form. B is wrong because the two forms are not interchangeable: there is a clear difference in register and nuance, and the classmate's suggestion meaningfully increases politeness. C is wrong because 「でしょうか」 does not embed the question indirectly or block a yes/no answer — the teacher can absolutely respond with 「はい」or「いいえ」. It remains a direct question, just a softer one. A useful tip: whenever you see 「でしょう」, think softness and deference. On politeness-register questions, ask yourself whether the form is asserting or wondering aloud — that contrast will consistently guide you to the right answer.

Question 4

A student is studying Japanese yes/no question patterns and encounters these two sentences:

  1. 「これはペンですか。」

  2. 「これはペンですか、えんぴつですか。」

How do these two sentences differ in function, and which sentence is a true yes/no question?

  1. Sentence 1 is a true yes/no question asking for confirmation that the item is a pen, while Sentence 2 is an either/or question offering two choices and does not expect a simple yes or no answer. (correct answer)
  2. Both sentences are yes/no questions because they both end with 「か」, but Sentence 2 is more polite because it offers alternatives to choose from.
  3. Sentence 2 is a true yes/no question because the final 「か」 is the only one that matters, and Sentence 1 is a rhetorical question not expecting a real answer.
  4. Sentence 1 is a true yes/no question, and Sentence 2 is also a yes/no question because the listener can simply say 「はい」 to confirm the first option presented.
Explanation: When studying Japanese question structures, it's essential to look beyond the particle 「か」 itself and examine the structure of the entire sentence to determine what kind of answer is expected. Sentence 1,「これはペンですか。」, presents a single subject and asks the listener to confirm or deny it — a textbook yes/no question. A natural response is 「はい、そうです。」or 「いいえ、違います。」Sentence 2, 「これはペンですか、えんぴつですか。」, uses the A か B か pattern, which presents two alternatives and asks the listener to choose between them. The expected answer is something like 「ペンです」or 「えんぴつです」— not yes or no. This makes A the correct answer: Sentence 1 is the true yes/no question, and Sentence 2 is an either/or (alternative) question. B is wrong because the presence of 「か」 alone does not determine question type. The structure around it matters enormously, and politeness has nothing to do with this grammatical distinction. C incorrectly claims only the final 「か」 determines meaning, ignoring that the A か B か pattern fundamentally changes the question's function — Sentence 1 is also not rhetorical at all. D is flawed because replying 「はい」to Sentence 2 would be unnatural and ambiguous; the sentence explicitly invites a choice, not a confirmation. As a study tip, always identify the sentence pattern before deciding question type. When you see two nouns separated by 「か」with a second 「か」at the end, recognize it immediately as an alternative question, not a yes/no question.

Question 5

A student wants to ask 'Is it not cold today?' in Japanese using a negative yes/no question. Which sentence correctly expresses this, and what does 「はい」 mean in the response 「はい、さむくないです。」?

  1. 「きょうはさむくないですか。」 is correct; 「はい」 in the response confirms the negative premise of the question, meaning 'Yes, that is right — it is not cold,' showing that Japanese 「はい」 aligns with the truth of the statement that follows. (correct answer)
  2. 「きょうはさむいですか。」 is correct; 「はい」 in the response means 'Yes, it is cold,' which confirms an affirmative state — but this contradicts the negative statement 「さむくないです」 that follows it in the response.
  3. 「きょうはさむくないですか。」 is correct; 「はい」 in the response means 'Yes, it is cold,' because Japanese 「はい」 always signals a positive real-world state regardless of whether the question was negative or affirmative.
  4. 「きょうはさむくですか。」 is correct; 「はい」 in the response confirms the negative, meaning 'Yes, it is not cold' — however, 「さむくです」 attempts to use the adverbial form before 「です」, which is only valid in negative constructions like 「さむくないです」.
Explanation: When working with negative yes/no questions in Japanese, two things matter: forming the negative correctly, and understanding how 「はい」 and 「いいえ」 function differently than English "yes" and "no." To say "Is it not cold today?", you attach 「か」 to the negative form 「さむくない」, giving you 「きょうはさむくないですか。」 — answer A's sentence. The key grammar point: い-adjectives form their negative by dropping 「い」 and adding 「くない」, so 「さむい」 becomes 「さむくない」. This is correct and complete. Now for the trickier part — what does 「はい」 mean in the response 「はい、さむくないです。」? Unlike English, where "yes" signals a positive real-world state, Japanese 「はい」 means the speaker agrees with the statement that follows. So here, 「はい」 confirms the truth of 「さむくないです」 — meaning "Yes, that's right, it is not cold." Answer A captures this perfectly. Answer B uses the affirmative question 「さむいですか」 instead, which asks "Is it cold?" — not the negative form the question requires. Answer C correctly identifies the sentence but misexplains 「はい」, falsely claiming it always signals a positive real-world state regardless of question type — this is the most common trap students fall into when comparing Japanese to English. Answer D uses 「さむくです」, which is grammatically invalid; 「さむく」 is the adverbial form and cannot directly precede 「です」. As a study tip: remember that Japanese 「はい」 affirms the following statement, not the real-world condition — always read what comes after it to understand the full meaning.

Question 6

Tanaka-san says to a friend: 「あしたは学校に来ますか。」 The friend responds: 「いいえ、来ません。」

If Tanaka-san had instead used rising intonation without 「か」 — saying 「あしたは学校に来ます↑」 — in informal spoken Japanese, which statement best describes the result?

  1. The sentence would still function as a yes/no question in informal spoken Japanese, as rising intonation alone can signal a question, but this pattern is less formal than using 「か」. (correct answer)
  2. The sentence would become grammatically incorrect because Japanese questions always require the particle 「か」 to be understood as questions at any register.
  3. The sentence would change meaning entirely and become a statement of certainty, because rising intonation in Japanese signals emphasis rather than a question.
  4. The sentence would function as a question only if the speaker also added 「ね」 at the end, since rising intonation alone is insufficient in any Japanese register.
Explanation: When studying Japanese question formation, it's important to recognize that formality level affects how questions are marked — not whether questions can be understood at all. Japanese has two main ways to signal a yes/no question: the sentence-final particle 「か」 (more formal/neutral) and rising intonation alone (casual spoken speech). In informal conversation, native Japanese speakers regularly drop 「か」 and rely on rising pitch to signal a question. So 「あしたは学校に来ます↑」 is perfectly natural among friends — it asks the same thing as 「来ますか」, just in a more casual register. This makes A correct: the sentence still functions as a yes/no question, but dropping 「か」 marks it as informal rather than neutral or polite. B is wrong because it overgeneralizes — it treats 「か」 as a grammatical requirement in all registers. In reality, 「か」 is a convention of formal/polite speech, not an absolute rule of Japanese grammar. Casual speech frequently omits it. C mischaracterizes how rising intonation works in Japanese. Rising pitch does not signal "emphasis" or "certainty" — it signals a question, just as it does in many other languages. Emphasis in Japanese is typically conveyed through stress, word choice, or particles like 「よ」, not rising intonation. D is wrong because it confuses 「ね」 with question formation. 「ね」 seeks agreement or confirmation, not yes/no answers — and it's not required for rising intonation to be interpreted as a question. Study tip: Think of 「か」 as the formal marker of a question, not the only marker. In casual Japanese, intonation does the work.

Question 7

A student reads the following informal exchange between two friends: A: 「明日、ひま?」 B: 「うん、ひまだよ。」

Which statement best explains the grammatical mechanism that makes A's utterance 「明日、ひま?」 function as a yes/no question in this informal context?

  1. The absence of 「です」 makes the sentence a question by default in Japanese, because incomplete sentences are always interpreted as questions in informal registers.
  2. The word 「ひま」 is an interrogative word in Japanese that inherently signals a question without needing any additional particles or intonation markers.
  3. The rising intonation represented by 「?」 replaces both the copula 「だ」 and the question particle 「か」, which are both dropped in casual speech, allowing the bare noun/na-adjective stem to function as a question. (correct answer)
  4. The particle 「か」 is implied after 「ひま」 and is simply not written; the sentence is grammatically complete with a silent 「か」 that native speakers mentally insert.
Explanation: When analyzing informal Japanese questions, focus on what grammatical elements are dropped in casual speech and what compensates for them. In formal Japanese, a yes/no question like this would be 「明日、暇ですか？」— the copula 「です」 plus the question particle 「か」 together mark it as a question. In casual speech, both are systematically dropped, leaving just the bare noun or na-adjective stem. What carries the question meaning instead is rising intonation, represented in writing by 「？」. This is exactly what C describes: rising intonation replaces both 「だ」 (the plain-form copula) and 「か」, allowing 「ひま」 alone to function as a question. This is a grammatically recognized and complete casual structure, not a fragment or accident. Choice A is wrong because incomplete sentences are not automatically interpreted as questions in Japanese — dropping elements works because of intonation and context, not simply incompleteness. A falling intonation on 「ひまだよ」 is a statement, not a question. Choice B is wrong because 「ひま」 (暇, meaning "free time" or "not busy") is not an interrogative word at all. Japanese interrogatives include words like 「何」「どこ」「誰」 — 「ひま」 is simply a na-adjective meaning "free/available." Choice D is tempting but misleading. There is no "silent か" that native speakers mentally insert — this implies the sentence is grammatically incomplete without it, when in fact casual question intonation is a fully legitimate alternative mechanism, not a workaround. Study tip: Remember the pattern: casual Japanese questions often = bare stem + rising intonation, while formal questions = stem + です/だ + か. Knowing what gets dropped, and why, is key on grammar questions like this.

Question 8

A student reads the following informal exchange between two friends: A: 「明日、ひま?」 B: 「うん、ひまだよ。」

A classmate argues that both sentences are yes/no questions because both end in 「ですか。」 Which response best evaluates this claim?

  1. The classmate is correct. Both sentences end in 「ですか」, which is the definitive marker of yes/no questions in Japanese, and the presence or absence of a question word in the sentence does not change this classification.
  2. The classmate is incorrect. Sentence 1 contains the question word 「だれ」, making it a WH-question (information question) that requires a specific answer and cannot be answered with yes or no, even though it ends in 「ですか」. Only Sentence 2 is a true yes/no question. (correct answer)
  3. The classmate is partially correct. Sentence 1 can be answered with yes or no if the listener already knows whose book it is, making it optionally a yes/no question depending on what information the listener chooses to provide.
  4. The classmate is incorrect. Neither sentence is a yes/no question because yes/no questions in Japanese must use plain-style 「か」 without 「です」 — the correct polite yes/no form would require a different sentence-final structure entirely.
Explanation: When reading Japanese passages, pay close attention to two things simultaneously: the sentence-final form and the presence or absence of question words. These two features together determine what type of question you're dealing with. Looking at the passage, neither sentence ends in 「ですか」 at all — Sentence 1 is 「明日、ひま?」and Sentence 2 is 「うん、ひまだよ。」 The first uses a rising-intonation informal question (just 「?」), and the second is actually a statement, not a question. The classmate's entire premise is wrong because they misread the sentences. This makes B the correct answer: the classmate is incorrect, and their stated reason — that both sentences end in 「ですか」— is simply false based on the text. Choice A fails on two levels: it accepts the classmate's false premise and also makes a broader error by claiming 「ですか」is the only marker of yes/no questions in Japanese, ignoring that informal rising intonation (as in Sentence 1) also creates questions. Choice C is a distractor that invents a question word 「だれ」that doesn't appear in the passage, then builds a flawed argument around it. Always re-read the passage carefully before accepting a claim about what it contains. Choice D introduces a fabricated grammatical rule. 「ですか」is perfectly standard for polite yes/no questions in Japanese — there is no rule requiring plain-style 「か」alone. Your study tip: before evaluating any linguistic claim about a passage, verify the claim against the actual text. Many traps on language exams are built on misquotations of the source material.

Question 9

Yuki is learning Japanese and wants to ask her friend if he likes sushi. She writes the following sentence: 「すしが好きですか。」

Which part of Yuki's sentence makes it a yes/no question in Japanese, and what would be the most natural affirmative response from her friend?

  1. The particle 「か」 at the end makes it a question; the most natural affirmative response is 「はい、好きです。」 (correct answer)
  2. The particle 「が」 makes it a question by marking the subject; the most natural affirmative response is 「はい、そうです。」
  3. The word 「好き」 rising in pitch makes it a question; the most natural affirmative response is 「はい、好きですか。」
  4. The particle 「か」 at the end makes it a question; the most natural affirmative response is 「はい、そうですか。」
Explanation: When learning Japanese, one of the first grammar points to master is how questions are formed — and it's much simpler than in English. Unlike English, which requires rearranging word order to ask a question, Japanese simply adds the sentence-ending particle 「か」 to a plain statement. So 「すしが好きです」 ("I like sushi") becomes 「すしが好きですか。」 ("Do you like sushi?") with just one added character. This makes A correct on both counts. The particle 「か」 is the question marker, and 「はい、好きです。」 is the most natural affirmative response. When answering, you echo the key predicate of the question — here, 「好きです」 — which directly confirms the thing being asked about. B is wrong because 「が」 is a subject marker, not a question particle. It tells you what is being discussed (sushi), not that a question is being asked. C reflects a common English-speaker assumption: in English, rising pitch alone can form a question, but Japanese doesn't rely on this grammatical mechanism — 「か」 is required. Additionally, responding with 「はい、好きですか。」 would mean "Yes, do you like it?" — turning the answer back into a question, which makes no sense. D is tempting because 「そうですか」 exists in Japanese, but it means "Is that so?" or expresses mild surprise — it's a response to new information, not a direct affirmative answer to a preference question. A useful rule of thumb: in Japanese, end your question with 「か」, and echo the predicate in your affirmative response.

Question 10

A student wants to form a yes/no question from the na-adjective sentence 「このまちはしずかです。」(This town is quiet.) Which transformation is correct, and which error do students most commonly make?

  1. The correct question is 「このまちはしずかですか。」 — simply adding 「か」. The most common error is producing 「このまちはしずかでないですか。」 by defaulting to a negative question form.
  2. The correct question is 「このまちはしずかなですか。」 — inserting 「な」 before 「です」 to mark the adjective type. The most common error is omitting 「な」 and producing 「このまちはしずかですか。」
  3. The correct question is 「このまちはしずかですか。」 — simply adding 「か」. The most common error is producing 「このまちはしずかいですか。」 by incorrectly treating the na-adjective like an i-adjective. (correct answer)
  4. The correct question is 「このまちはしずかくですか。」 — converting the adjective to its adverbial form before adding 「か」. The most common error is keeping the plain form and producing 「このまちはしずかですか。」
Explanation: When forming yes/no questions in Japanese, the key rule is simple: in polite speech (です・ます style), you attach the question particle 「か」 directly to the end of the sentence without changing anything else. This question tests whether you understand how na-adjectives behave in this transformation — and whether you can spot a confusion between na-adjective and i-adjective patterns. For な-adjectives like 「しずか」, the polite affirmative form is 「しずかです」. To make it a yes/no question, you simply add 「か」: 「このまちはしずかですか。」 Nothing about the adjective stem changes. That makes C correct — and it also correctly identifies the most common student error: treating 「しずか」 like an i-adjective. A is wrong because it misidentifies the typical error. While producing a negative question form is a possible mistake, it is not the most common one students make when first learning adjective question forms. The real trap is the i-adjective confusion that C identifies. B is incorrect because inserting 「な」 before 「です」 — producing 「しずかなですか」 — is actually ungrammatical. The 「な」 in na-adjectives only appears when the adjective directly modifies a noun (e.g., 「しずかなまち」). It does not appear before 「です」 in predicate position. D is entirely fabricated. 「しずかく」 is not a valid form; the adverbial form of na-adjectives uses 「に」 (「しずかに」), and neither form is used when simply asking a yes/no question. Your study tip: remember that 「な」 appears before nouns, not before 「です」 — and that question formation in polite Japanese is always just adding 「か」.
