Question

Shown below are images of chairs produced using typical manufacturing processes. Which of the following statements is/are TRUE?

• A. P is designed for stackability; R requires many operations to manufacture.
• B. S is not designed for stackability; Q has more than five number of parts.
• C. P is designed for stackability; Q requires many operations to manufacture.
• D. R is not designed for stackability; P has less than five number of parts.

Hint:

For manufacturing-related questions, analyze the design complexity and the number of parts in each object to assess the manufacturing difficulty and stackability.

Answer 1

The Correct Option is A, C

Step 1: Observe the design and construction of each chair. P is a simple wooden chair designed for easy stackability, while R has a more complex design, requiring multiple manufacturing operations.
Step 2: Q, made of molded plastic, has many more parts compared to the other chairs, indicating the need for complex manufacturing processes.
Step 3: Based on the observations, the correct answers are (A) and (C).

Answer 2

The four chairs shown are a simple wooden chair (P), a molded plastic armchair (Q), a woven wicker seat on a metal tube frame (R), and a black folding chair (S). To judge stackability and manufacturing effort, it helps to look at each chair's construction separately.

1. P is designed for stackability; R requires many operations to manufacture: The wooden chair P has a simple, straight-legged frame with no arms or wide base flare, which is exactly the kind of simple silhouette that stacks cleanly on top of an identical chair. The woven chair R, on the other hand, combines a bent and welded metal tube frame with a separately woven wicker seat and back, which means shaping the tubing, welding the joints, and weaving the seat are all separate operations, adding up to many manufacturing steps.
2. S is not designed for stackability; Q has more than five number of parts: S is a folding chair, and folding chairs are usually designed to fold flat for storage rather than stack, so the first half is plausible, but Q is a single molded plastic shell, which is normally produced as one continuous piece with very few separate parts, not more than five.
3. P is designed for stackability; Q requires many operations to manufacture: P's stackable claim holds as before, but Q, being one molded plastic shell formed in a single injection molding step, is actually one of the simplest chairs here to manufacture, not one that needs many operations.
4. R is not designed for stackability; P has less than five number of parts: R's tube-and-weave frame is not particularly suited to stacking, which is plausible, but P, a basic four-legged wooden chair, is typically built from more than five parts once the seat, backrest, back legs, front legs, and stretchers are all counted separately.

Weighing all four, only the first option pairs two claims that both hold up: P's plain shape makes it stackable, and R's mixed materials and welded, woven construction genuinely require many manufacturing operations.

So the correct statement is "P is designed for stackability; R requires many operations to manufacture."
