限界（げんかい）means 'limit, the utmost boundary.' 体力の限界 means 'the limit of one's physical stamina.' The athlete is reaching/pushing their physical limit. This is the natural collocation with 体力.

• 1制限（せいげん）means 'restriction, limitation (imposed from outside).' 体力の制限 is not a natural phrase; 制限 implies an externally imposed constraint, not an inherent limit.
• 3境界（きょうかい）means 'boundary/border (between two areas or concepts).' This is used for territorial or conceptual borders, not for physical stamina.
• 4境目（さかいめ）means 'boundary line/dividing line (visible or conceptual).' This is used for distinguishing between two things, not for expressing a limit of endurance.

• 限界げんかい — limit, the utmost boundary
• 制限せいげん — restriction, limitation (externally imposed)
• 境界きょうかい — boundary, border (between areas/concepts)
• 境目さかいめ — boundary line, dividing line
• 体力たいりょく — physical strength, stamina

Option 1 「固めた」(かためた) is correct. The phrase 「決意を固める」(けついをかためる) is a fixed collocation meaning 'to firm up one's resolve' or 'to make up one's mind firmly.' The sentence means: 'That event triggered his firm resolve to become a doctor.' The verb 固める is used when strengthening an abstract feeling or intention such as 決意 (resolve), 意志 (will), or 信頼 (trust).

• 2「まとめた」(まとめた) means 'to organize, to put together, to summarize.' You can まとめる things like 意見 (opinions) or 資料 (materials), but 決意をまとめる is not a natural collocation. Resolve is something you firm up, not something you organize.
• 3「仕上げた」(しあげた) means 'to finish, to complete (a task/product).' It is used for completing work or a product (e.g., 仕事を仕上げる). You cannot 'finish completing' a resolve in this way, so it does not fit.
• 4「合わせた」(あわせた) means 'to match, to combine, to adjust.' You might 合わせる schedules or opinions, but 決意を合わせる ('to match one's resolve') is not a standard expression and does not fit the context.

• 決意けつい — resolve, determination, decision
• 固かためる — to make firm, to strengthen, to solidify (a feeling/intention)
• まとめる — to organize, to put together, to summarize
• 仕上しあげる — to finish, to complete (a task or product)
• 合あわせる — to match, to combine, to adjust
• 出来事できごと — event, happening
• きっかけ — trigger, opportunity, chance

分担 (ぶんたん) means 'sharing/dividing a task or responsibility among people.' 夫婦で分担する means 'the couple shares (the work).' Since both spouses work, they divide housework and child-rearing — 分担 is the correct word.

• 1分別 (ふんべつ) means 'judgment, discernment' (e.g., 年齢相応の分別) or 'separating garbage by type.' It does not mean sharing tasks between spouses.
• 2区別 (くべつ) means 'distinguishing between things, telling A from B.' It is about differentiation, not division of labor.
• 3区分 (くぶん) means 'classification, zoning, partitioning into categories.' It is used for dividing areas/categories, not for sharing household duties.

• 分担ぶんたん — sharing/dividing a task or responsibility
• 分別ふんべつ — judgment, discernment; separating by type
• 区別くべつ — distinguishing between things
• 区分くぶん — classification, zoning, partitioning

ふさわしい (相応しい) means 'suitable, fitting, worthy'. The sentence means 'The person most suitable for the next company president would be Suzuki, who has a lot of experience.' The pattern 〜にふさわしい (suitable for ~) fits perfectly with the target role '次の社長' (next president).

• 2等しい (ひとしい) means 'equal'. You cannot say 次の社長に等しい人 because it implies the person is 'equal to the next president', which is not a natural collocation and does not convey the intended meaning of being a good fit for the position.
• 3ありがちな means 'common, apt to happen, likely'. Saying 次の社長にありがちな人 is unnatural; it would imply a person who is 'commonly associated with being the next president', which is not how this word is used.
• 4当たり前な (あたりまえな) means 'natural, obvious, ordinary'. While one might say 'it's obvious Suzuki will be president', the phrase 次の社長に当たり前な人 is grammatically awkward and semantically incorrect; 当たり前 does not take に to mean 'suitable for a role'.

• ふさわしい — suitable, fitting, worthy (often used as 〜にふさわしい)
• 等ひとしい — equal, equivalent
• ありがちな — common, apt to occur, likely
• 当たり前な（あたりまえな） — natural, obvious, ordinary, matter-of-course
• 社長しゃちょう — company president
• 経験豊富けいけんほうふな — experienced, rich in experience
