Why the "Purchase" part cannot be E? KarishmaB
­I think it's because if the raw material is expensive then the end cost of carbon axes will be high regardless of the means i.e, via production or supply. It's true that in-house price might be a little cheaper but it will be expensive anyway. There may not be a huge difference between the cost of the product if produced internally or supplied. On the other hand, in B - it says the largest suppliers have been able to make them affordably so definitely it gives us evidence that it will definitely be cheaper to purchase.

Does this make sense?

why manufacture column can not choose [Carbon-fiber drivetrain components, such as axles, are relatively new to the automotive industry and very few of the company’s current suppliers are able to make them.] ?

If very few of the company's current suppliers are able to make them, it weakens the PURCHASE as well as the MANUFACTURE options

Because it will be expensive either way - PURCHASE or MANUFACTURE

Purchase: “Carbon-fiber component production is prohibitively expensive in small and medium quantities, so only the largest suppliers have been able to produce them affordably.”

Reasoning:
If producing carbon-fiber axles in small quantities is extremely costly, it would not be economically feasible for the company to manufacture them in-house, especially since they only need them for a small fleet of compact vehicles. Also, large suppliers can leverage economies of scale, producing carbon-fiber axles at a significantly lower cost. Therefore, it would make the most financial sense for the company to purchase the axles from these suppliers instead of trying to produce them itself.

Manufacture: “The manufacturer’s own engineering department designed the innovative technique for using carbon fibers in axles, a technique that the company would like to keep proprietary.”

Reasoning:
If the company developed a unique and innovative technique for making carbon-fiber axles and wishes to protect this proprietary knowledge, it would avoid outsourcing production to third-party suppliers. Manufacturing the axles in-house allows the company to maintain full control over its intellectual property and prevent competitors from accessing its proprietary methods.

Sajjad1994 KarishmaB Can you'll throw some light on why E won't be correct.
I was choosing B, but with the stipulation of quantities, which would be out of context, since there is no mention of production capacity, I chose E.

E isn’t correct because it’s about raw material cost, which affects both options equally. Whether the company makes or buys the carbon-fiber axles, the expensive material is a fixed factor, so it doesn’t tilt the decision either way.

B fits perfectly because the manufacturer plans to replace the steel axles only on its small fleet of compact vehicles. Producing in-house for such a small quantity would be uneconomical, while large suppliers that already operate at scale could offer lower per-unit costs. Hence, B supports Purchase, not E.

Can Someone help answer why A and C are incorrect for Manufacture?

My rationale for A -
Quote:
"Carbon-fiber drivetrain components, such as axles, are relatively new to the automotive industry and very few of the company’s current suppliers are able to make them."
- This could point at lack of availability for purchase options and hence Manufacturing could be an option

My rationale for C -
Quote:
"If the carbon-fiber axles prove to be successful in dramatically increasing fuel economy, the manufacturer will consider using the new axles on other vehicles it produces."

Company could very well want to expand the usage to other products in the future, and hence could be a rationale for it to stick to this reason.

Another blocker I felt for this question was there was almost nothing from the stimulus that could hint at why we should go for Manufacture/Purchase in some scenarions. This is contrary to the pattern I have observed in TPA questions, where there is some hint given to which option one should go for.

A: “Very few” does not mean “none”, some capable suppliers exist, so purchase remains feasible. The statement gives no in-house advantage on cost, quality, capacity, etc., so it’s weak for Manufacture.

C: It’s conditional and speculative. “If successful” and “will consider” do not create a present reason to manufacture. Even with future expansion, suppliers could scale. No immediate cost, capacity, quality, etc. rationale for in-house, so it’s weak for Manufacture.

Strongest manufacture reason is D (protect proprietary technique).
