At an enormous research cost, a leading chemical company has developed a manufacturing process for converting wood fibers into a plastic. According to the company, this new plastic can be used for, among other things, the hulls of small sailboats. But what does the company think sailboat hulls used to be made of? Surely the mania for high technology can scarcely go further than this.

18. The author’s opinion of the manufacturing process described in the passage is based primarily on the fact that

(A) plastic is unlikely to be durable enough for high-quality sailboat hulls
(B) the research costs of developing the process outweigh any savings possible from the use of the plastic
(C) a small sailboat is not normally regarded as a high-tech product
(D) hulls for small sailboats can be made from wood without converting it into plastic
(E) many other spheres of human activity are in far greater need of technological research

19.Which of the following, if true, would most seriously weaken the author’s conclusion?

(A) The plastic produced by the process is considerably lighter, stronger, and more watertight than wood.
(B) The wood used in producing the plastic is itself in increasingly short supply.
(C) The cost of the manufacturing process of the plastic increases the cost of producing a sailboat hull by 10 to 15 percent.
(D) Much of the cost of the research that developed the new process will be written off for tax purposes by the chemical company.
(E) The development of the new plastic is expected to help make the chemical company an important supplier of boat-building materials

This is pretty much the reinterpretation of authors conclusion. Also check:

(A) The plastic produced by the process is considerably lighter, stronger, and more watertight than wood.(B) The wood used in producing the plastic is itself in increasingly short supply.
(C) The cost of the manufacturing process of the plastic increases the cost of producing a sailboat hull by 10 to 15 percent.
(D) Much of the cost of the research that developed the new process will be written off for tax purposes by the chemical company.

In 19. A is the only answer that provides a good reason for new development. Also check:

18. The author’s opinion of the manufacturing process described in the passage is based primarily on the fact that:
I had A and D as the final list. After analysing those two, D is the final answer.

19.Which of the following, if true, would most seriously weaken the author’s conclusion?
Ans is A. The rest of the points supports author's conclusion.

A doubt. Where in the paragraph is it mentioned that hulls can be made from wood?
are we allowed to bring in external factors in such a question?

(refering to 18. The author's opinion of the manufacturing process described in the passage is based primarily on the fact that ...)

I chose B & E that seem compare the new plastic to other plastics used to make the boats. However,I understand the OAs for D & A where the plastic is compared directly to the wood.

At an enormous research cost, a leading chemical company has developed a manufacturing process for converting wood fibers into a plastic. According to the company, this new plastic can be used for, among other things, the hulls of small sailboats. But what does the company think sailboat hulls used to be made of? Surely the mania for high technology can scarcely go further than this.

Which of the following, if true, would most seriously weaken the author’s conclusion?

A) The plastic produced by the process is considerably lighter, stronger, and more watertight than wood.
If the plastic has all these enhanced properties in comparison with wood, then it definitely is a better material for building hulls of small sailboats.
B) The wood used in producing the plastic is itself in increasingly short supply.
Tends to strengthen the author's conclusion.
C) The cost of the manufacturing process of the plastic increases the cost of producing a sailboat hull by 10 to 15 percent.
Strengthens the author's conclusion.
D) Much of the cost of the research that developed the new process will be written off for tax purposes by the chemical company.
Totally irrelevant.
E) The development of the new plastic is expected to help make the chemical company an important supplier of boat-building materials.
The development of this plastic may allow the Company to become a leading supplier of other boat-building materials different from hulls, for which this plastic might not be a suitable material. Therefore, this does not necessarily weaken the author's conclusion. This is the only reason that I could think of for discarding this option. If anyone can come up with other reasons, please explain them to us.

Please share your view on the reasoning above, especially on options A and E, which are the best candidates.
