Innovators are developing a new cutting machine that hopes to distinguish weeds from agricultural crops by use of the latest technology in sensors. The differences in shade of color will be the basis for making the distinction. In their pitch to venture capitalists, the innovators point to the ability to lower labor costs by completely removing the need for manual weeding.

Which of the following is a consideration in favor of the company's implementing its plan to develop the prototype?

(A)

Some plants change the shade of their color considerably as they grow.

(B)

When weeding may not be found necessary laborers engaged in that work can find other jobs in agriculture during the growing season.

(C)

While weeds are being removed manually, the prime consideration to identify them is the shape of the leaf and its overall size.

(D)

Genetic manipulation will allow any species of plants to be bred economically, so that it can have a distinctive shade, color and other characteristics remaining unaltered.

(E)

Different species of weeds show considerable variations in the shade of their color.

Hi,
I'd like some thoughts on how to eliminate some answer choices and get to the eventual answer.
Many thanks.

A - Could Weaken. If the color of the plants keeps changing, the sensors might not be able to differentiate between crops and weeds effectively.

B - Out of scope. We are only concerned about the effectiveness of the technology.

C - Could weaken. If the weeds are identified by their shape and not by their color, the technology might not be very effective.

D - Strengthens. If the crops can be grown to be of uniform color, then they can be easily distinguished from the weeds and hence the technology would be more effective.
E - Could Weaken. If the color of the weeds are not consistent, then the technology might have trouble sensing them.

Kudos Please... If my post helped.

Although D looks like the correct one, I would like to argue for B

The question asks Which of the following is a consideration in favor of the company's implementing its plan to develop the prototype?
What is in favor -- it nowhere says how effective the plan is.

(B)When weeding may not be found necessary laborers engaged in that work can find other jobs in agriculture during the growing season. --- this is in favor of the plan
If we negate it, the workers won't have any job which means that it will not work in favor of the company.

Let's say the owner of the company is Mr. Burns from the Simpsons.. Will he really care if workers are out of a job?.. In fact, if he can find ways to fire people and still get the same output, he would prefer those ways.. In short, we do not care about the workers...

If its D, then it means that genetic manipulation is necessary for their venture to be successful. In contrast, for E, it means that their technology can utilize existing natural variation in color. Both D and E imply the technology "depends" on something else to be successful. However, genetic manipulation being time consuming and has to the bottleneck of social opposition, it means it is more vulnerable for failure. In contrast, natural variation has not such issue. Hence, E is in more favor than D.

Hi,

The argument states that the cutters will identify weeds from crops by color and that this will cut down on labor costs.

Answer (D) says that it is possible to create plants with distinctive colors that are unchanged in other ways.

This provides support for the argument because this potentially provides a way that crops can be made even more distinctive from weeds.

Answers (A) (C) and (E) all give reasons why the cutters might NOT be effective.

And answer (B) is irrelevant.
