TOPIK Practice – TOPIK I 어휘 [Vocabulary] 1–5 (10/4/2026) – coast guard missing plane

정답: B. 실종

How to solve: The sentence indicates that the plane has disappeared and has not yet been found. Therefore, the word describing the state of being 'missing' or 'unaccounted for' is appropriate.

A — '발견' means 'discovery'. This is the opposite of the current situation where the plane is still missing.

B — '실종' means 'missing' or 'disappearance'. This accurately describes the state of a plane that has disappeared and has not been found.

C — '조사' means 'investigation'. While an investigation might happen, it doesn't describe the plane's state of being unfound.

D — '성공' means 'success'. This word is irrelevant to the context of a missing plane.

정답: A. 실종, 수색

How to solve: The first blank needs a word to describe the plane that the Coast Guard is looking for. The second blank needs a verb describing the action of actively looking for something over a wide area.

A — '실종된' (missing) accurately describes the plane. '수색했습니다' (searched) accurately describes the action of the Coast Guard looking for it. This pair fits the context perfectly.

B — '발견된' (discovered) would mean the plane has already been found, which contradicts the idea of '찾기 위해' (to find). '조사' (investigation) is a follow-up action, not the primary action of looking.

C — '구조' (rescue) is the goal after finding, not the state of the plane before searching. '사고' (accident) is a noun and doesn't fit the verb structure.

D — '조사' (investigation) doesn't describe the state of the plane being looked for. '발견' (discovery) doesn't fit the action of actively searching.

정답: C. 흔적, 발견

How to solve: The sentence implies that something small belonging to the missing plane was found on the sea. The first blank should be something that can be 'small' and belongs to a disappeared object. The second blank should describe the action of finding it.

A — '구조' (rescue) and '성공' (success) do not fit the context of '작은 ~이 ~되었다' (a small ~ was ~ed).

B — '탑승자' (occupant) refers to a person, not a small item or trace. '조사' (investigation) doesn't fit the 'discovery' context.

C — '흔적' (trace, sign, debris) fits '작은 ~이'. '발견되었습니다' (was discovered/found) fits the action of finding something. This pair is coherent.

D — '항공기' (aircraft) is too large for '작은 ~이'. '실종' (missing) is a state, not an action performed on a trace.

정답: B. 사고, 항공

How to solve: The first blank needs a word to describe an event that causes services to be suspended. The second blank needs a word to specify the type of service that was suspended in relation to a plane.

A — '수색' (search) and '발견' (discovery) do not logically lead to '모든 서비스가 중단되었습니다' (all services were suspended).

B — '사고' (accident, incident) is a common reason for service suspension. '항공' (aviation, air) appropriately describes the type of service affected by a plane accident. This pair makes the most sense.

C — '발견' (discovery) doesn't typically cause service suspension. '구조' (rescue) is a specific action, not a type of service that is generally suspended.

D — '실종' (missing) refers to a state, and while related, '사고' is a more direct cause for widespread service suspension. '조사' (investigation) is a process, not a service.

정답: C. 구조, 탑승자

How to solve: The sentence describes an action that resulted in safely 'saving' someone. The first blank should be the type of work involved in saving people. The second blank should be the people who were saved.

A — '수색' (search) is about finding, not directly saving. '흔적' (trace) cannot be '구할 수 있었습니다' (saved).

B — '조사' (investigation) is not a saving operation. '항공기' (aircraft) is an object, not typically 'saved' in the context of human rescue.

C — '구조' (rescue) is the work specifically aimed at saving people. '탑승자' (occupants/passengers) are the people on board a vehicle who can be rescued. This pair fits the sentence perfectly.

D — '발견' (discovery) is finding, not saving. '사고' (accident) is the event itself, not a person or thing that is saved.
