N3 Reading · Test 48

Option 3 (③ 自然と遊ぼう) is correct. Yan's family has four requirements: (1) the program falls between August 14–18, (2) spending time in nature, (3) an overnight program (泊まれるプログラム), and (4) adult fee at or below 10,000 yen. Program ③ runs August 15–16 (within the date range), is a 1泊2日 program (overnight ✓), involves outdoor activities like boating, fishing, and climbing trees (nature ✓), and costs 10,000 yen per adult. The key point is that 以下（いか）means 'at or below / no more than,' so exactly 10,000 yen satisfies the condition of '10000円以下.'

• 1① 森を歩こう runs Aug 1–15 (partially within range) and is cheap (800 yen), but it is a 日帰りプログラム (day trip), not an overnight program. This fails the '泊まれるプログラムがいい' requirement.
• 2② 自然を観察しよう runs Aug 16–31 (partially within range) and is cheap (600 yen), but it is also a day trip program, not overnight. This fails the overnight requirement.
• 4④ 星空を観察しよう runs Aug 17–18 (within range) and is an overnight 1泊2日 program, but the adult fee is 12,000 yen, which exceeds the 10,000 yen limit. This fails the budget requirement.

• 以下いか — at or below; no more than (includes the boundary value)
• 泊とまれる — can stay overnight (potential form of 泊まる)
• 日帰ひがえり — day trip (going and returning on the same day)
• 1泊2日（いっぱくふつか） — one night, two days (overnight program)

Option 4 is correct. 「森を歩こう」is program ①, which falls under the 日帰りプログラム (day trip program). The passage states two key things for day trip programs: (1) '予約はいりません' (no reservation needed), and (2) the application method is '当日、自然の家の受付で直接お申込みください' (apply directly at the reception desk on the day). For payment, '日帰りプログラムは、当日、お申し込みと一緒に現金でお支払いください' (pay in cash on the day together with your application). Option 4 correctly combines these: apply on the day and pay in cash at the same time.

• 1This describes the procedure for 1泊2日 programs (reserve by phone one week in advance, pay by bank transfer), not for day trip programs. 森を歩こう is a day trip program that requires no reservation.
• 2This incorrectly mixes the day trip application method (apply on the day) with the overnight payment method (bank transfer within 3 days). Day trip programs require cash payment on the day, not bank transfer.
• 3This says to reserve by phone by the day before, but day trip programs require no reservation at all ('予約はいりません'). The cash-on-the-day payment part is correct, but the reservation requirement is wrong.

• 日帰りプログラム（ひがえりプログラム） — day trip program (no overnight stay)
• 予約よやく — reservation, booking
• 当日とうじつ — on the day (of the event)
• 現金げんきん — cash
• 銀行振り込み（ぎんこうふりこみ） — bank transfer
