Step 1: Understanding the Concept:
This is an analogy question relating an adjective to a noun. The adjective describes a state of sameness or identity with respect to the noun.
Step 2: Key Formula or Approach:
Define the relationship in the stem pair: CONGRUENT: DIMENSIONS. In geometry, figures that are "congruent" have the exact same "dimensions" (size and shape). The relationship is "Things that are X have identical Y."
Step 3: Detailed Explanation:
Let's test the "Things that are X have identical Y" relationship with the options:
- (A) Do things that are convenient have identical time? No, something "convenient" happens at a suitable or opportune time, not an identical time.
- (B) This pair does not fit the structure. An axis is used to define a coordinate.
- (C) Is a conglomerate made of identical parts? No, a "conglomerate" is a thing consisting of a number of different and distinct parts. This is the opposite relationship.
- (D) Do things that are coincident have identical chance? No, "coincident" means occurring at the same time. It is often attributed to chance, but this doesn't fit the relationship structure.
- (E) Are things that are coeval of identical age? Yes, "coeval" means having the same age or date of origin. This is a perfect match.
Step 4: Final Answer:
Just as congruent things have identical dimensions, coeval things have an identical age. The relationship is perfectly parallel.
