あずけた (預けた, past tense of 預ける) means 'entrusted' or 'left in someone's care.' The sentence says 'Since I can't take it on the trip, I entrusted my pet dog to a friend.' 預ける is the standard verb for temporarily leaving something (a pet, luggage, money) in someone's keeping.

• 2ふざけた (ふざけた) means 'joked around' or 'fooled around' (past tense of ふざける). You cannot 'fool around' a pet dog to a friend — the particle に requires a verb of transfer/entrustment.
• 3くっつけた (くっつけた) means 'attached' or 'stuck (something) onto' (past tense of くっつける). This does not fit the context of leaving a pet with a friend.
• 4よびかけた (呼びかけた) means 'called out to' (past tense of 呼びかける). While you can call out to a friend, you cannot 'call out' a pet dog to someone — the structure 友人にペットの犬を呼びかける is grammatically and semantically wrong.

• 預あずける — to entrust, to leave in someone's care
• つれていけない（連れていけない） — cannot take along (potential negative of 連れていく)
• ふざける — to joke around, to fool around
• くっつける — to attach, to stick together
• 呼よびかける — to call out to, to appeal to

から (空) is the correct choice. 空になったビン means 'the bottle that became empty.' 空になる (からになる) is the standard expression for 'to become empty,' describing a container with its contents used up. The sentence says 'When you finish drinking, please throw the empty bottle here.'

• 1あき (空き) also relates to emptiness, but it is used as a prefix or noun in compounds (e.g., 空き瓶 あきびん 'empty bottle,' 空き時間 あきじかん 'free time'). The form あきになった is not standard Japanese; the correct expression is からになる. This is a deliberate distractor exploiting the overlap between 空/空き.
• 2なし (無し) means 'without' or 'none' (the 連用形 of ない). なしになった is not standard grammar; the correct form would be なくなった. It also does not naturally describe a bottle becoming empty.
• 3すき (好き) means 'liked/fond of' (as in 好きな食べ物). すきになった means 'came to like (something),' which makes no sense for a bottle.

• 空から — empty (as an i-adjective/na-adjective usage for containers)
• 空からになる — to become empty
• 空あき — empty/vacant (used as prefix in compounds, e.g., 空き瓶)
• 飲み終わったら（のみおわったら） — when you finish drinking

いつのまにか means 'before one knew it /不知不觉に.' The sentence says 'Last night, while reading a book in bed, I fell asleep before I knew it.' This fits perfectly because falling asleep while reading is something that happens without one noticing.

• 1いつのことか means 'when was it?' — a rhetorical question about an unclear past time. It does not describe an unnoticed process and makes no sense before 寝てしまった.
• 3いつまでも means 'no matter how long / forever.' It implies persistence, not an unnoticed change, so it cannot modify 寝てしまった.
• 4いつでも means 'anytime / whenever.' This expresses availability or possibility, not the unintended nature of falling asleep.

• いつのまにか — before one knew it;不知不觉に
• いつのことか — when was it? (rhetorical)
• いつまでも — no matter how long; forever
• いつでも — anytime; whenever

改造 (かいぞう) means 'to remodel / convert / modify a structure or object.' The sentence says 'My company remodeled/converted a warehouse and uses it as an office.' This is the correct word for physically altering a building's structure for a new use.

• 1改正 (かいせい) means 'revision/amendment' and is used for laws, regulations, or rules (e.g., 法律を改正する). It cannot apply to a physical building.
• 3改善 (かいぜん) means 'improvement' of conditions, processes, or situations (e.g., 環境を改善する). While a warehouse could be 'improved,' 改善 does not convey the structural remodeling needed to turn it into an office.
• 4改定 (かいてい) means 'revision' of prices, fees, or plans (e.g., 運賃を改定する). It does not apply to physical structures.

• 改造かいぞう — remodeling; conversion; modification (of a structure/object)
• 改正かいせい — revision; amendment (of laws/regulations)
• 改善かいぜん — improvement (of conditions/processes)
• 改定かいてい — revision (of prices/fees/plans)

きつく is the adverbial form of きつい, meaning 'tight.' The sentence says 'Perhaps because I've gained a little weight recently, my pants have become tight.' Gaining weight would logically make clothing feel tighter, so this is the natural choice.

• 1ずるく is the adverbial form of ずるい, meaning 'sly / cunning.' This describes a person's character or behavior, not clothing fit.
• 2ゆるく is the adverbial form of ゆるい, meaning 'loose.' This is the opposite of what gaining weight would cause — pants would become tighter, not looser.
• 3にぶく is the adverbial form of にぶい, meaning 'dull / blunt.' This applies to knives, senses, or reactions, not to how clothing fits.

• きつい — tight; strict; intense
• ずるい — sly; cunning
• ゆるい — loose; lenient
• にぶい — dull; blunt; sluggish

ノック (knock) fits the context: 'When entering a room, please knock on the door.' ノックする is a common katakana verb meaning 'to knock (on a door).'

• 1プラス (plus) does not fit — you don't 'plus' a door.
• 3サイン (sign) does not fit — you don't 'sign' a door when entering.
• 4カープ (curve) does not fit — unrelated to doors or entering a room.

• ノック — knock (on a door)
• プラス — plus, addition
• サイン — signature, sign
• カープ — curve

しつこい (執こい/しつこい) means 'persistent, stubborn, relentless.' The sentence describes someone who keeps coming back to ask even after being told 'no' repeatedly — a classic description of a しつこい person.

• 2こまかい (細かい) means 'detailed, fine, small' — describes attention to detail, not persistence.
• 3すまない (済まない) means 'sorry, apologetic' — does not describe a personality trait of persistence.
• 4おもたい (重たい/重い) means 'heavy (weight or mood)' — unrelated to the context of someone repeatedly asking.

• しつこい — persistent, stubborn, relentless
• 細こまかい — detailed, fine, small
• 済すまない — sorry, apologetic
• 重おもたい — heavy (literal or figurative)

あふれ (溢れ) means 'overflowed.' The sentence says: 'Due to yesterday's heavy rain, the river water overflowed, and nearby houses suffered damage.' When a river overflows due to heavy rain, あふれる is the natural verb.

• 1うなり (唸り) means 'groan' or 'roar' (e.g., a river roaring). While a river can 'うなる,' it doesn't collocate with the causal structure here and doesn't lead to houses being damaged in the way described.
• 2つもり means 'intention' or 'plan.' It makes no sense in this context — river water cannot have intention.
• 3こぼれ (零れ) means 'spilled' (like liquid from a cup). It is used for small-scale spilling, not a river overflowing its banks.

• あふれる — to overflow, to flood over
• うなる — to groan, to roar
• こぼれる — to spill, to overflow (small container)
• 家屋かおく — houses, buildings
• 被害ひがい — damage, harm

比較 (ひかく) means 'comparison.' The pattern「Aと比較してみましょう」means 'let's try comparing (it) with A.' The sentence reads: 'Let's try comparing the shape of the coastline around here with 50 years ago.' 比較する naturally takes と to mark what something is compared against.

• 1測定 (そくてい) means 'measurement.' You measure something, but you don't 'measure with 50 years ago' — 測定 doesn't take と in this way.
• 2一致 (いっち) means 'match, coincide.' While 一致する can take と, '一致してみましょう' (let's try matching) doesn't fit the context of examining coastline change over time.
• 4統一 (とういつ) means 'unify, standardize.' You unify things into one standard; it doesn't take と for comparison and doesn't fit the context.

• 比較ひかく — comparison
• 測定そくてい — measurement
• 一致いっち — agreement, match, coincidence
• 統一とういつ — unification, standardization
• 海岸線かいがんせん — coastline

おかまいなく is a polite expression meaning 'please don't go to any trouble' or 'don't bother on my account.' The guest is declining the offer of more tea, saying 'Oh, please don't bother — I'll be leaving soon.' This is the standard phrase a guest uses to politely decline hospitality.

• 1おまたせしました means 'I'm sorry to have kept you waiting.' This would be said by the person who made others wait, not by a guest declining tea.
• 3かしこまりました means 'certainly, I understand' — a polite acceptance used by service staff accepting a request. It would never be said by a guest declining an offer.
• 4ごえんりょなく means 'please don't hold back / make yourself at home.' This is said by the HOST to encourage the guest, not by the guest themselves.

• おかまいなく — please don't go to any trouble (polite refusal of hospitality)
• おまたせしました — sorry to have kept you waiting
• かしこまりました — certainly; I understand (polite acceptance)
• ごえんりょなく — please don't hold back; make yourself at home
• おかわり — a refill (of drink/food)
