Question Type: Strengthen

Argument: A plan to develop a laptop having iris scanners than can distinguish one from another. Saves money and theft.

A. There is considerable variation in the color and patterns present in most people's irises. - Correct. Since there is considerable variation in color and patterns, the iris scanners can work effectively.

B. The size of people's irises tends to change noticeably over the course of the day. - Opposite.

C. In-person security services will not suffer from technological glitches when allowing access to laptops. - Out of context. The argument doesn't even discuss about 'in person security services' and we do not know whether those services require access after the implementation of iris scanners.

D. Colored contacts allow people to change their eye color, without altering any of the other characteristics of their iris. - Opposite.

E. Insurance and security companies provide other services to companies in addition to protecting laptops. - Irrelevant.

Yes, that's right. A strengthen question can be dealt by stating the assumption or by defending the conclusion by providing additional information.
Here, A is the required assumption and hence falls in the first category of the strengthen type.

Imo A

The prototype laptop uses iris scanners to distinguish one user from another. The implication of this laptop is that it will help in reducing insurance and security cost as only authorized users will be able to turn on the laptop.

Now in support question we can support assumption, premise, and conclusion. We can also remove alternate result to reinforce the conclusion.
So in this question we will support the assumption of the argument.

A Per this choice variation in iris helps to distinguish two different individuals so this is the necessary assumption. If we negate this choice the whole argument falls apart.

B is irrelevant to the argument.

C Out of scope

D Irrelevant

E Out of scope

A technology company plans to develop a prototype laptop that uses iris scanners that can distinguish one user from another. The inventor of this laptop claims that it will reduce insurance and security costs at offices, as only authorized users will be able to turn on the laptop, making it a less appealing target for thieves.

Type- Strengthen
Boil it down - This laptop will reduce insurance and security costs at offices as only authorized users will be able to turn on the laptop

A. There is considerable variation in the color and patterns present in most people's irises. - Correct -- This is a necessary condition
B. The size of people's irises tends to change noticeably over the course of the day. -- Incorrect - weakens
C. In-person security services will not suffer from technological glitches when allowing access to laptops. - Out of scope
D. Colored contacts allow people to change their eye color, without altering any of the other characteristics of their iris. - Incorrect- At best this choice is a mild weakner a because color is just one of several characteristics
E. Insurance and security companies provide other services to companies in addition to protecting laptops. -- Out of scope

Answer A

Official Explanation Magoosh:




Answer = (A). The conclusion here belongs to the inventor: companies that use the new computer will run fewer security risks. Her evidence is that it uses iris scanners so that only authorized users can use it. To strengthen the connection between reduced security risks and only selected individuals accessing computers, we have to make the assumption that irises can be distinguished from one another with some degree of precision. (A) provides us with this answer in slightly different words.

Because the system is meant to allow only certain individuals to access the machines, changing irises (B) might actually present a problem for the system, if the system were incapable of accounting for this change. If this were the case, this choice would weaken, not strengthen, the company’s case for developing this prototype. It may be iris size makes no difference, in which case this choice is irrelevant, or it may make a difference, in which case this choice is a weakener. Either way, it's not a strengthener.

It's not clear how relevant choice (C) is. First of all, the company is not developing the laptop in tandem with in-person security services—or if it is, the passage does not mention it; thus, this choice may or may not be directly relevant. Furthermore, there's something eerily unrealistic about this option: what technology on Earth suffers from zero glitches?? Even if there is a small glitch rate, say under 1% of the time, that would be an annoyance, but not enough to impact overall sales and the success of the product. Thus, choice (C) does not have to be strictly true.

People might change their eye color, even users of these machines (D), but we aren’t told how this would affect their access to the machines, or how the machines would deal with this additional factor. Nevertheless, if anything, this would weaken the case for the company to develop these computers, so it’s not what we’re looking for.

We’re not concerned with what other companies do (E); this question is only asking us about this company, in particular. It’s possible that the development of this product would affect other companies, or the consumer’s use of other companies, but it’s not necessary to consider this to identify and strengthen the conclusion in this argument.
