The correct answer is 4 (性). 危険性 (きけんせい) means 'danger' or 'risk' and is formed by attaching 性 (せい, meaning 'nature/property') to 危険. The sentence means: 'If you use this tool incorrectly, there is a risk of injury.' The pattern 危険性がある ('there is a risk/danger') is a common fixed expression.

• 1素 (す) does not form the word 危険素 — this is not a valid Japanese compound.
• 2態 (たい) does not form the word 危険態 — this is not a valid Japanese compound.
• 3状 (じょう) does not form the word 危険状 — this is not a valid Japanese compound.

• 危険性きけんせい — danger, risk (the property of being dangerous)
• 性せい — suffix meaning 'nature, property, -ness'
• 器具きぐ — tool, implement, appliance

The correct answer is 1 (未). 未経験 (みけいけん) means 'inexperienced / having no experience.' The prefix 未 (み) means 'not yet' and attaches to nouns to indicate something has not yet happened or been done. The sentence means: 'Even a person with no experience can do this task easily.'

• 2不 (ふ) means 'not/un-' but 不経験 is not an established Japanese word.
• 3少 (しょう) would suggest 'little experience,' but 少経験 is not a standard compound; the natural word would be 経験が少ない.
• 4低 (てい) means 'low' but 低経験 is not an established compound.

• 未経験みけいけん — inexperienced, having no prior experience
• 未み — prefix: not yet, un-
• 経験けいけん — experience

The correct answer is 3 (切れ). 期限切れ (きげんぎれ) means 'expired' (lit. 'deadline-cut'). The suffix 切れ (ぎれ) indicates that something has run out or been used up. The sentence means: 'This card is expired, so I cannot use it.'

• 1越え (こえ) means 'exceeding/passing' but 期限越え is not an established compound.
• 2折れ (おれ) means 'breaking/snapping' and does not combine with 期限.
• 4終え (おえ) relates to 'finishing' but 期限終え is not an established Japanese word.

• 期限切きげんぎれ — expired (past its deadline)
• 切ぎれ — suffix indicating something has run out / been exhausted
• 期限きげん — deadline, expiration date

The correct answer is 2 (高). 高性能 (こうのうせい) means 'high performance' and is a very common compound. 高 (こう) means 'high' and combines with 性能 to form a standard word. The sentence means: 'This is video shot with a high-performance camera.'

• 1優 (ゆう) means 'excellent/superior' but 優性能 is not an established compound.
• 3良 (りょう) means 'good' but 良性能 is not an established compound.
• 4上 (じょう) means 'upper/high' but 上性能 is not an established compound.

• 高性能こうのうせい — high performance
• 高こう — prefix: high
• 性能のうせい — performance, capability

The correct answer is 3 (おき). 一日おき (いちにちおき) means 'every other day' (with one day skipped in between). The suffix おき indicates an interval. The sentence means: 'Mori apparently cleans every day, but I'm busy so I do it every other day.' Note: 一日おき can sometimes be ambiguous (every other day vs. every two days), but in common usage it means 'every other day.'

• 1あき does not form a valid expression 一日あき in this context.
• 2とり does not form a valid expression 一日とり.
• 4とび (飛び) can mean 'skipping' in some contexts, but 一日とび is not the standard expression for 'every other day.'

• 一日いちにちおき — every other day (one day skipped between occurrences)
• おき — suffix indicating an interval (every X intervals)
• 掃除そうじ — cleaning

思いきって means 'taking the plunge / mustering one's courage to do something.' The speaker had been worrying about something they couldn't tell anyone, so finally consulting a close friend required courage — they took the bold step. 思いきって＋V (consulted) fits perfectly.

• 2うっかり means 'carelessly / inadvertently / by mistake.' Consulting a friend about a long-held worry is intentional, not accidental, so this doesn't fit.
• 3せっかく means 'with much effort / going to the trouble of,' typically followed by expressions of appreciation or regret (せっかく…のに/のだから). It doesn't modify a verb like 相談してみた in this context.
• 4知らず知らず means 'unconsciously / without realizing it.' The speaker was fully aware they were consulting their friend, so this is wrong.

• 思おもいきって — taking the plunge; mustering courage to do something
• うっかり — carelessly; inadvertently; by mistake
• せっかく — with much effort; going to the trouble of (often with のに/のだから)
• 知らず知らず（しらずしらず） — unconsciously; without realizing it

訂正(ていせい) means 'correction (of an error),' especially fixing mistakes in text. The sentence says there was a kanji error in the manuscript, so correcting it with a red pen = 訂正した. This is the standard word for fixing individual mistakes.

• 1交換(こうかん) means 'exchange / swapping (one thing for another).' You don't 'exchange' a kanji error with a red pen.
• 2改訂(かいてい) means 'revision (of a published book/document),' a large-scale update of content, not fixing a single character error with a pen.
• 3変換(へんかん) means 'conversion / transformation' (e.g., kana-to-kanji conversion on a keyboard). It doesn't mean correcting a mistake.

• 訂正ていせい — correction (of an error in text)
• 交換こうかん — exchange; swapping
• 改訂かいてい — revision (of a published work)
• 変換へんかん — conversion; transformation

めざして (目指して) means 'aiming for / targeting.' The athletes are aiming for victory in the next tournament, so they practice late every day. Nをめざして is the correct pattern for 'aiming at a goal.'

• 1とらえて (捉えて) means 'capturing / grasping / catching.' You don't 'capture' a championship as a goal in this construction.
• 3みはって (見張って) means 'watching carefully / keeping an eye on.' Athletes don't 'watch over' a championship.
• 4にぎって (握って) means 'gripping / grasping (with the hand).' This is physical grasping, not aiming for a goal.

• 目指めざして — aiming for; targeting (a goal)
• 捉とらえて — capturing; grasping; catching
• 見張みはって — watching carefully; keeping guard
• 握にぎって — gripping; grasping (with the hand)

一気に means 'in one breath / all at once / in one go.' The novel was so interesting that the reader read it all the way through without stopping — 一気に読んでしまった (read it all in one sitting).

• 2一時的に means 'temporarily.' Reading a novel to the end is not a temporary action.
• 3一斉に means 'simultaneously / all at once (by multiple people).' This is one person reading, not a group acting together.
• 4一方的に means 'one-sidedly.' This describes an unequal relationship or action, not how one reads a book.

• 一時的いちじてきに — temporarily
• 一斉いっせいに — simultaneously (by a group)
• 一方的いっぽうてきに — one-sidedly

蓄えて (たくわえて) means 'accumulating / storing up / building up.' The sentence says to gather information and accumulate necessary knowledge in advance (〜ておく) — 知識を蓄えておく is the natural collocation.

• 2招いて (まねいて) means 'inviting (a person).' You don't 'invite' knowledge.
• 3抱えて (かかえて) means 'holding/carrying (under one's arm) / having (a problem or burden).' Knowledge is not something you 'hold under your arm.'
• 4結んで (むすんで) means 'tying / binding.' You don't 'tie' knowledge.
