Proscenium is related to Stage in a specific structural way. Which of the following word pairs shows the same type of relationship?

Introduction / Context:
This analogy involves architectural and structural terms. Proscenium refers to a specific part or feature of a Stage in a theatre. You must find the pair that reflects a similar part to whole or entrance to main structure relationship among the options.

Given Data / Assumptions:
1) The Proscenium is the arch or frame that separates the stage from the audience in a traditional theatre.

Concept / Approach:
The pair Proscenium : Stage expresses a relationship where the first term is a structural feature at the front of the second term, often forming an entrance like frame. In architecture, a Portico is a porch or entrance structure that leads into a House. This closely mirrors the idea of a Proscenium leading into the acting space of a Stage, which makes Portico : House the correct analogy.

Step-by-Step Solution:
Step 1: Recall that a Proscenium is the front part or arch of a theatre Stage that frames the acting area. Step 2: Understand that this creates a part to whole relationship where the Proscenium is a special structural feature of the Stage. Step 3: Examine the options. Lamp : Table is an object placed on a surface, not a structural part of the table. Lines : Bed is unclear and does not form a common architectural relationship. Step 4: Portico is a roofed structure at the entrance of a building, often forming a passage or porch leading into a House. Step 5: Compass : Needle reverses the part to whole order, since Needle is a part of a Compass, which does not match Proscenium : Stage. Step 6: Therefore, Portico : House is the pair that best mirrors the structural entrance relationship of Proscenium : Stage.

Verification / Alternative check:
Restate each pair as a phrase. Proscenium of a Stage. Portico of a House. Both expressions sound natural and refer to architectural features associated with the main structure. Lamp of a Table is not a fixed part. Lines of a Bed is not a standard phrase. Needle of a Compass has reversed order for the part to whole relationship.

Why Other Options Are Wrong:
Lamp : Table describes a separate object resting on furniture, not an integral structure. Lines : Bed has no clear, standard meaning in everyday description. Compass : Needle inverts the direction of the relationship, since the needle is part of the compass, while Proscenium is part of the Stage, not the other way round. Only Portico : House is a clear architectural parallel.

Common Pitfalls:
Some test takers may focus on the idea of part to whole only and consider Compass : Needle, forgetting that the order matters. In Proscenium : Stage, the stage is the whole and the proscenium is the part at the front. In Compass : Needle, the compass is the whole and needle is the part, reversing the order. Careful attention to the direction of the relationship is essential in analogy questions.

Final Answer:
Thus, the correct pair that shares the same type of relationship as Proscenium : Stage is Portico : House. The answer is Portico : House.
