N4 Grammar · Test 21

Option 1 (と) is correct. The pattern 〜と here expresses a condition/trigger: 'when you do ~, ...'. ちょっと見ると means 'when you look briefly' (it seems easy, but it's actually difficult). The と conditional is used for natural or habitual sequences — 'when X happens, Y is the case.'

• 2ば is a conditional (〜ば meaning 'if'), but it requires the 仮定形 (conditional stem) of a verb, not the dictionary form. ちょっと見るば is ungrammatical; it would need to be 見れば.
• 3が is the subject marker. ちょっと見るが would mean 'I look briefly, but...' — a contrastive conjunction, which does not fit the sentence structure here (there is no contrasting clause before かんたんそう).
• 4は is the topic marker. ちょっと見るは does not form a grammatical construction that leads into かんたんそう. The と conditional is what links the two clauses.

• ちょっと見る（ちょっとみる） — to take a quick look
• 〜と — when/if (conditional expressing a natural sequence)
• かんたんそう — seems easy (簡単 + そう)
• むずかしい — difficult

Option 4 (なら) is correct. なら is a conditional/topic particle meaning 'if you're talking about ~' or 'as for ~'. みちこならもう出かけましたけれど means 'If it's Michiko you're asking about, she has already gone out.' This is the natural response when someone asks whether a specific person is available — なら picks up the topic mentioned by the caller.

• 1が would make みちこがもう出かけました, meaning 'Michiko (as the subject) already left.' While grammatically possible, it does not convey the natural 'as for ~' topic-shifting nuance that なら provides in this conversational context. The speaker is responding to a request about Michiko, so なら (topic conditional) is the idiomatic choice.
• 2を marks the direct object of a transitive verb. 出かける is intransitive, so を cannot be used here. みちこをもう出かけました is ungrammatical.
• 3でも means 'even ~'. みちこでももう出かけました would mean 'even Michiko has already left,' implying surprise that Michiko (among others) left. This does not fit the context of simply answering whether Michiko is available.

• 〜なら — if it's ~; as for ~ (topic conditional, picks up a mentioned topic)
• いらっしゃる — to be (honorific); to be present
• 出でかける — to go out; to leave

Option 1 (お高う) is correct. This tests the polite (丁寧) form of i-adjectives before ございます. The rule is: drop the final い of the adjective and add うございます. 高い → 高 + うございます = 高うございます. With the polite prefix お, it becomes お高うございます, meaning 'is (a little) expensive' in very polite speech (often used by shop staff).

• 2お高いございます is incorrect. You cannot simply insert ございます after the plain adjective form 高い. The correct contraction is 高うございます (drop い, add う).
• 3高いにございます is ungrammatical. The particle に cannot connect an adjective to ございます in this way.
• 4高いでございます is ungrammatical in standard keigo. The correct polite form uses the う-contraction (高うございます), not で.

• お高うございます（おたこうございます） — it is expensive (very polite form of 高いです, used in formal/customer-service speech)
• ワイシャツ — dress shirt
• 少すこし — a little
