N1 Vocabulary · Test 40

驚嘆 is read きょうたん, meaning 'amazement/astonishment/admiration'. The sentence says 'I can only be amazed at the height of his insight.' Option 2 is correct.

• 1きよたん — Wrong reading; 驚 is きょう, not きよ.
• 3きょうだん — This is the reading of 共談 or could evoke 強談; wrong voicing (だ instead of た) for 嘆.
• 4きょだん — Wrong reading of both characters; 驚 is きょう not きょ.

• 驚嘆きょうたん — amazement, astonishment, admiration

盛大に（せいだいに）means 'grandly/on a large scale,' and is the standard adverb for describing how a festival or event is held. 盛大に行われる — 'to be held grandly' — perfectly matches a festival with thousands of participants singing and dancing.

• 1鮮烈に（せんれつに）means 'vividly/strikingly,' describing a strong, memorable visual or psychological impression. It does not describe the scale or manner of holding a festival.
• 2絶大に（ぜつだいに）means 'immensely/overwhelmingly,' but it typically modifies nouns like power, influence, or trust (絶大な力, 絶大な人気). It is not used to describe how an event is conducted.
• 4熱烈に（ねつれつに）means 'passionately/fervently,' describing the intensity of feelings or support (熱烈な歓迎). While a festival is passionate, 熱烈に行われる is not the standard expression for a grand-scale festival; 盛大に is the correct collocation.

• 盛大せいだいに — grandly, on a large scale (for events/festivals)
• 鮮烈せんれつに — vividly, strikingly (leaving a strong impression)
• 絶大ぜつだいに — immensely, overwhelmingly (modifies power/influence/trust)
• 熱烈ねつれつに — passionately, fervently (intense feeling/support)

The correct option is 3. 「せかせかと」 means acting hastily, hurriedly, or restlessly. This perfectly matches the context of the sentence, which describes the person as 「忙しそうに動き回っている」 (moving around looking busy). Someone who is busy and in a hurry moves around hastily, making this the best fit.

• 1「のろのろと」 means 'slowly' or 'sluggishly'. This contradicts the latter half of the sentence, which says the person is moving around looking busy (忙しそうに動き回っている).
• 2「すいすいと」 means 'smoothly', 'swiftly', or 'easily' (like swimming or progressing without difficulty). While it implies moving with ease, it does not convey the sense of being busy or in a hurry that the sentence requires.
• 4「ふらふらと」 means 'unsteadily', 'aimlessly', or 'dizzily'. This implies a lack of purpose or physical instability, which contradicts the image of someone actively and busily moving around.

• せかせかと — hastily, hurriedly, restlessly
• のろのろと — slowly, sluggishly
• すいすいと — smoothly, swiftly, easily
• ふらふらと — unsteadily, aimlessly, staggeringly
• 忙いそがしそうに — looking busy, seemingly busy
• 動き回る（うごきまわる） — to move around, to be active
