Japanese Synonym and Homophone Quiz | Vocabulary for Purpose, Evidence, Rules, and Resolution, Set 7

A describes the underlying idea, purpose, and reason for undertaking the program, so 「趣旨」 is appropriate. B concerns the central meaning or key point of the report, so 「主旨」 fits. 「趣旨」 can also refer to what a text or speech intends to say, which can bring the terms close in some contexts, but this question explicitly contrasts a program's purpose with a document's central conclusion.

A concerns the detailed circumstances and sequence of events, including negotiations and reasons that led to the current decision, so 「経緯」 is appropriate. B records how the construction progressed and changed over a period, so 「経過」 fits. 「過程」 can describe a path toward a result, but it does not directly convey the circumstances among the parties that A specifically requires.

The latter action is 「検証」 because measured trial results are used to test whether the hypothesis is correct. The earlier comparison of several conditions to decide whether adoption would be advisable is 「検討」. 「吟味」 can also mean examining something carefully, but 「検証」 most directly fits the stated condition of testing an explicit hypothesis against measurements.

The first public announcement of the lecture's date and time is 「告知」, the act of notifying people of information. The repeated explanation and confirmation intended to make the safety rules widely known throughout the company is 「周知」. 「通達」 mainly refers to instructions from a superior body to subordinate bodies, while 「公示」 is commonly used when a public body formally makes something known; neither captures the contrast tested here.

A is an obligation to obey and follow rules, so 「遵守」 is appropriate. B uses an international standard as a design basis or reference, so 「準拠」 fits. Both contain the idea of following something, but 「遵守」 emphasizes observing a rule, while 「準拠」 emphasizes relying on a standard as the basis for one's work.

A describes a confused situation becoming organized and settled, so 「収束」 is appropriate. Because the investigation continues, not every aspect has necessarily ended. B states that the outbreak itself has ended completely, so 「終息」 fits. Both terms may be used for outbreaks in actual reporting, but the question explicitly separates stabilization from complete cessation.

「策定」 is used when a policy or plan is developed and determined, so the disaster-prevention plan is 「策定した」. 「制定」 is used when laws, ordinances, or rules are established, so the ordinance is 「制定した」. 「施行」 means bringing an already established law into force, which differs from the stage of newly establishing the ordinance.

A is 「委託」, the broad act of having an outside party perform work such as cleaning. B is 「委任」 because a person entrusts defined authority to a representative and creates a document equivalent to a power of attorney. The general meanings of the two words overlap, but the question specifies their typical contexts: outsourced services and delegated authority.

A uses a past accident as a precedent and lesson against which the current decision is considered, so 「事故に鑑みて」 is appropriate. B treats the present survey as a concrete factual basis, so 「調査結果を踏まえて」 fits. 「省みる」 mainly means reflecting on one's own conduct, while 「顧みる」 means turning one's attention to the past or one's surroundings; neither expresses both stated conditions as precisely.

A concerns unilaterally canceling a contract or agreement, so 「破棄」 is appropriate. B concerns discarding physical items that are no longer needed, so 「廃棄」 fits. 「破棄」 can also mean tearing up and discarding unwanted documents, but this question explicitly contrasts cancellation of a contract with disposal of obsolete equipment.
