Difficulty:


A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating 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. There is a considerable degree of variation in shade of color between weeds of different species.
B. The shade of color of some plants tends to change appreciably over the course of their growing season.
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.
D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

D)...IMO A) is weakening the usage of the prototype, because it wont be able to distinguish between weeds and plants.

I see why A is a weakener. If you read carefully, it states that weeds have variety of shades. If they do, it would be hard for the machine to distinguish the weeds from the actual crops since there are so many species of weed that are different from each other. I thought A was the correct answer because when I read it, i thought it said that there is a considerable variations of shades in the weed and the crops.

I would go for E.

E as it makes economic sense to free farm workers from doing de-weeding work,if they can tend to other agricultural duties.

D - I didn't pick D because , genetic engineering is required to see the efficacy of the prototype, which IMO not a strong reason to develop a prototype , and more-over what is the need to change the color of crops , which at present might be distinct from any of the weeds.

I believe D should be the answer, and here is why

The argument states that the machine will be able to distinguish plants from weeds solely on the differences in the shade of color. D states that plants can be bred to have a distinct shade of color. This means that a plant can be bred with a distinct shade of color that is completely different from that of the weeds. Thus, this development will favor the development of this machine.

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

A. There is a considerable degree of variation in shade of color between weeds of different species.

Tells us nothing about the color of the plants (as we are told, the new technology uses differing colors between crops and weeds). The trap - Eliminate

B. The shade of color of some plants tends to change appreciably over the course of their growing season.

Makes the technology non-efficient. Eliminate

C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.

So what? WE are concerned with the new technology, which uses color to distinguish weeds from crops. WE dont care about manual distinction - Eliminate.

D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.

Straight Answer. Crops can be bred to have distinct colors, which can enable the technology separate crops from weeds.

E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

We are not concerned about manual processes - Eliminate (irrelevant)


It's a straight (D).

Hi Zarrolou,

I find option A to be irrelevant to this argument but OG says it is a weakener. If this was a weakener question I am not sure if I would have chosen A.

Could you please explain why A is a weakener ? Is it because if all weeds were of the same color then it would be easy to distinguish them from the crops or is there some other reason for considering this a weakener ?

Well B looks like a good weaken option.

Appreciate your help. :)

Thanks,
Sandeep.


You're close, yes--A is a weakener because if the weed species have a considerable variation in shades, it will be more difficult for the machine to do what the inventor claims (distinguish between weeds and plants). Note, it doesn't follow that the machine would fail to do the job, just that it would be harder for it to do so (i.e. the risk of it not doing its job properly increases).

I'm not an instructor or anything, but be mindful of making value judgments when considering weaken/strengthen questions or choices. There is no requirement that a choice greatly strengthen or weaken to some large degree--we only want a choice that "moves the needle" (even if only slightly!) in one direction or the other.

Reasoning: a prototype with optical sensors and microprocessors can distinguish weeds from crop plants by differences in shade of color.

Prethinking:
--> So, the bigger the diff. in shade of color between weeds and crop, the easier it will be for a mashine to distinguish between them.
--> fewer colors of weeds > many colors for the mashine to ba able to distinguish between weeds and crop.

Question Type: Strengthen --> so, new information is appreciated here


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

A. There is a considerable degree of variation in shade of color between weeds of different species --> weakens the argument - see the reasoning stated above
B. The shade of color of some plants tends to change appreciably over the course of their growing season --> is it easier for mashine to make a distinction it this case ? NO.
C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds --> irrelevant. We are concerned about the shade of color. Actually, it's a weakener.... more factors that must be distiguished by the mashine.
D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics --> CORRECT. Distinctive shade of color makes it easier for the mashine to make such distinction.
E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary --> irrelevat. "Zero" information about the mashines and a distinction....

also go with A..... this is the assumption on which the argument is based. on this basis the company is developing the prototype of the machine...

As much as D looks tempting, A can be directly inferred from the question stem.

christoph, I totally agree.

We need to be able to distinguish between weeds and plans.

D for me too.

I would go for C as it is the only choice which would favour the company's decision to develop the prototype.

A fails because it does not favor co. as it makes the comparison between crops and weeds difficult
B fails as the machine still wont be able to distinguish between crops and weeds
D fails because it is out of the scope.
E. unnecessary information..!

i go with D

A. is weakining company proposed implementation. Diferencies in color of diferent species will not allow this equipment to work correctly.
b. is the same as above
c. is weakining because it is showing us that there is other common technic to distinguish weeds from crop.
d is out of scope
e. is giving some justification to implement this equipment

what is OA?

I would go with E, because of the obvious ecnomomic benefit.

Don't agree with A becuase the sentence says variation of color in weeds of different species, not between weeds and crops.
