Which of the following most logically completes the passage?

Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators. In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.

A. large moths are generally able to maneuver better in flight than smaller moths
B. large moths are proportionally much more common in warm climates than in cool climates
C. small moths are more likely than large moths to be effectively camouflaged while on vegetation
D. large moths typically have wings that are larger in proportion to their body size than smaller moths do
E. most predators of moths prey not only on several different species of moth but also on various species of other insects

CR: rework [#permalink] New post 21 Sep 2004, 03:26
A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company’s warranty. The reworked jobs are invariably satisfactory. When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.

The argument above assumes which of the following?

A. There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
B. There is no company that successfully competes with Ace Repairs for complex repair jobs.
C. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.
D. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.
E. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

:yes
1. B : Larger moths have higher optimal body temperatures, they will be vegetated with early higher temperature and so must be more common in warm climate.
2. A : if quality of engineers vary with kind of work whether firt time / repair, conclusion wont hold good.

Please post OAs

1-A
2-A
1- The "but" is to make an addition to the advantage of larger moths's agility because of their larger size; they also have optimal body temperature(another pro) which will allow them to better control their flight
2- Well explained by Dharmin

A. large moths are generally able to maneuver better in flight
than smaller moths
-- Nothing in the passage comparing flight techniques !

B. large moths are proportionally much more common in warm climates
than in cool climates
-- This is the key. Warm climates will enable large moths to have the optimal body temperature much more quickly than cold climates

C. small moths are more likely than large moths to be effectively camouflaged while on vegetation
-- Ability to camouflage has nothign to do with temperature

D. large moths typically have wings that are larger in proportion to their body size than smaller moths do
-- Same as above, wing size has no relation with temperature

E. most predators of moths prey not only on several different species of moth but also on various species of other insects
- Out of scope !

To me, B is out of scope for the first question. Why would the author mention something about climates when there was no allusion to it throughout the excerpt?

1. B
CDE are out os scope.

Larger moths fly faster (thereby escaping predators), BUT they ALSO have higher optimal body temperature which explains why ___________
I expected to see something like, "which explains why they are hiding more in vegetations, there by succeptible to non-flying predators".

The generic moth has better flight because of optimal temperature and not higher temperature. If the air temperature falls, their temperature will not be optimal and hence they hide in vegetations.
The larger moth has higher than the optimal temperature, hence they are supposed to be in vegetations all the time. If they are out and flying (and even escaping predators) they should be in warm climate first. Then the argument of "better manuever" comes into picture.

climate may seem out of scope, but actually they are in scope, present in the stem in the form of air temperature.

gotcha. Just re-read the first sentence and yes B makes sense

paul, i think you made a ggod argument in the first argument concerning the moth. b could never be true because if smaller moth require less temperature than the big moth, then in warm whether, we shd see either more smaller moth or an equal amout of the sizes of moth.
overall i find this argument a little off balance. whatis the source of this question?

For the first question, higher optimal body temperature means easier to become inactive in colder climate, therefore it flows naturally that larger moth would need warmer climate (B), and it doesn't flow at all to say that the high optimal temperature makes them manuver easier in flight, which is something totally undiscussed at all. If OA is A then OA is wrong. It may be helpful if we know the source of the question.

A for sure right here.
Each species of moth has an optimal body temperature for effective flight

but they also have higher optimal body temperatures, which explains why ______.

Nowhere in the passage says the higher the optimal body temperature is the more effective they fly. It merely says that if the temperature drops below the optimal then they can't fly.

I am unsure about A & B , but would pick B.Large moths under the same high temperature would survive more than smaller moths .

These questions suck
None of the choices for the moth question really fit.
