猛烈 is read もうれつ. The sentence means 'I was intensely/fiercely angry at that attitude.' 猛烈(もうれつ) is an adverb/noun meaning 'fierce, intense, violent'.

• 1もれつ is a misreading that drops the う from もう.

• 1こうふく is a distractor that sounds like 幸福(こうふく) 'happiness' or 降伏(こうふく) 'surrender'.
• 2かくふく is a fabricated reading.
• 3かいふく is the reading of 回復 'recovery', a near-synonym in context, making it a deliberate distractor.

• 克服こくふく — overcome, conquer

崩れ is read くずれ. 崩れる(くずれる) means 'to collapse, crumble, fall apart'. The sentence means 'It crumbles easily, so please be careful when carrying it.'

センサー (sensor) is the correct choice. The sentence means 'When gas leaks, a sensor detects it and an alarm sounds.' A sensor is precisely the device that perceives/detects (感知する) physical conditions like gas and triggers an alert.

• 1レーダー (radar) is used for detecting distant objects (aircraft, ships, weather) using radio waves. It is not used for detecting gas leaks in a building.

壮大な (そうだいな, grand/magnificent) is the correct choice. It collocates naturally with 夢 (dream) to describe a grand, large-scale ambition such as building a rocket and flying it into space. The phrase 壮大な夢 is a common collocation.

• 1絶大な (ぜつだいな) means 'immense, overwhelming' and is used for power, influence, or effect (e.g., 絶大な威力, 絶大な人気). It does not naturally modify 夢.
• 2盛大な (せいだいな) means 'grand, lavish' and is used for events or ceremonies (e.g., 盛大なパーティー, 盛大な式典). It does not describe a dream.
• 3雄大な (ゆうだいな) means 'majestic, imposing' and typically describes natural scenery or landscapes (e.g., 雄大な景色). It is less natural for 夢.

• 壮大そうだいな — grand, magnificent, large-scale
• 絶大ぜつだいな — immense, overwhelming (power/influence)
• 盛大せいだいな — grand, lavish (events/ceremonies)
• 雄大ゆうだいな — majestic, imposing (scenery/landscape)

ここちよく (心地よく) is correct. It means 'pleasantly, comfortably.' The sentence says 'The gentle melody pleasantly reached my ears and led me to sleep.' ここちよく響く (pleasantly resonate) fits the soothing context perfectly.

• 2いさぎよく (潔く) means 'gracefully, resolutely' (e.g., 潔く諦める, give up gracefully). It does not describe how a melody sounds.
• 3喜ばしく (よろこばしく) means 'joyful, welcome' and describes situations or news, not how something resonates in one's ears.
• 4輝かしく (かがやかしく) is an uncommon adverbial form of 輝かしい (brilliant, radiant). It does not collocate with 響く in this context.

• ここちよく — pleasantly, comfortably (心地よい)
• いさぎよく — gracefully, resolutely (潔い)
• 喜よろこばしく — joyfully, welcome (喜ばしい)
• 輝かがやかしく — brilliantly, radiantly (輝かしい)
• 響ひびき — resonance, echo

従事 (じゅうじ) is correct. 従事する takes the particle に and means 'to be engaged in / to work on (a task or field of study).' 研究に従事している (is engaged in research) is a standard collocation, fitting 'My brother, as a scientist, is engaged in genetic research.'

• 2勤務 (きんむ) means 'service, duty' and 勤務する means 'to work (at a workplace).' It takes で (e.g., 会社で勤務する) and refers to being on duty at a location, not engaging in a specific research task.
• 3在籍 (ざいせき) means 'enrollment, registration' (e.g., 学校に在籍する). It refers to being registered at an institution, not to doing research.
• 4就労 (しゅうろう) means 'finding employment, starting work.' It refers to the act of getting/holding a job, not to being engaged in a specific research activity.

• 従事じゅうじ — engagement in (a task); 〜に従事する = to be engaged in
• 勤務きんむ — work, duty; 〜で勤務する = to work at
• 在籍ざいせき — enrollment, registration
• 就労しゅうろう — employment, starting work

にじんで (滲んで) is correct. にじむ means 'to run (ink), to blur, to bleed.' When a postcard gets wet in the rain, the ink runs and becomes hard to read. インクがにじむ is the natural collocation.

• 1暴れて (あばれて) means 'to act violently, to rampage.' It is used for people or animals behaving wildly, not for ink.
• 3震えて (ふるえて) means 'to tremble, to shake.' Ink does not tremble.
• 4ゆがんで (歪んで) means 'to be distorted, warped.' While a postcard itself could warp, the sentence specifically says the インク (ink) did this, and ink running/bleeding is にじむ, not ゆがむ.

• にじむ — to run (ink), to bleed, to blur
• 暴あばれる — to act violently, to rampage
• 震ふるえる — to tremble, to shake
• ゆがむ — to be distorted, to warp
