保存（ほぞん）means 'to preserve, to keep something in good condition so it doesn't deteriorate,' used especially for food, data, historical artifacts, etc. Option 3, 'この食品は必ず冷蔵庫で保存してください' (Please be sure to preserve this food in the refrigerator), is the correct usage — food is a prime object of 保存.

• 1お金（お金）is not something you 保存; the natural verb is 貯金（ちょきん）する or 貯蓄（ちょちく）する, meaning 'to save money.' 保存 implies preventing physical deterioration, not financial saving.
• 2For keeping a seat for a friend, you would use 席を取っておく or 席を確保（かくほ）する. 保存 does not apply to reserving a physical spot.
• 4For conserving physical energy, the appropriate word is 体力を温存（おんぞん）する or 体力を蓄（たくわ）える. 保存 is not used for stamina or energy.

日課（にっか）means 'daily routine, a task one does every day as a habit.' Option 4, '毎朝30分体操することを日課にしている' (I've made doing 30 minutes of exercise every morning my daily routine), is the correct usage — 日課 refers to a personal habitual daily activity.

• 1A bus schedule/timetable is 時刻表（じこくひょう）or ダイヤ, not 日課. 日課 is a personal routine, not a published schedule.

• 2For stars shining brilliantly, you would use きらびやかに or 美しく or まばゆく. 多彩 describes variety of types, not visual sparkle.
• 3For readers having various interpretations, the correct word is 多様な（たような）or さまざまな, meaning 'various, diverse (kinds).' 多彩 implies richness/colorfulness of activities or talents, not multiplicity of interpretations.

乗り継ぐ（のりつぐ）means 'to transfer from one vehicle to another to continue a journey.' Option 3, 'バスと電車を乗り継いで、やっと目的地に着いた' (I transferred between a bus and a train and finally reached my destination), is the correct usage — it specifically describes switching between different modes of transport.

• 1Overshooting your station by falling asleep is 乗り過ごす（のりすごす）, meaning 'to ride past one's stop.' 乗り継ぐ means transferring, not missing a stop.
• 2Having a friend take over driving is 運転を代わる（かわる）or 代わってもらう. 乗り継ぐ is about changing vehicles, not switching drivers within the same vehicle.
• 4This describes many people simply riding (乗る) the train, not transferring. 乗り継ぐ requires switching from one vehicle to another, so '電車を乗り継ぐ' without a second vehicle is incorrect.

• 乗り継ぐ（のりつぐ） — to transfer (from one vehicle to another)
• 乗り過ごす（のりすごす） — to ride past one's stop
• 代かわる — to take over, to substitute
