Although the number of large artificial satellites orbiting the Earth is small compared to
the number of small pieces of debris in orbit, the large satellites interfere more seriously
with telescope observations because of the strong reflections they produce. Because
many of those large satellites have ceased to function, the proposal has recently been
made to eliminate interference from nonfunctioning satellites by exploding them in space.
This proposal, however, is ill conceived, since _______.
A. many nonfunctioning satellites remain in orbit for years
B. for satellites that have ceased to function, repairing them while they are in orbit
would be prohibitively expensive
C. there are no known previous instances of satellites’ having been exploded on
purpose
D. the only way to make telescope observations without any interference from debris
in orbit is to use telescopes launched into extremely high orbits around the Earth
E. a greatly increased number of small particles in Earth’s orbit would result in a
blanket of reflections that would make certain valuable telescope observations
impossible

Its a close one between D and E - I go for E but very reluctantly. I'd be interested to see the OE for this.

E. exploding satellite makes more interferences; hence, ill conceived.

I was stuck between D and E but chose D.

For E to work, we have to assume that exploding them will indeed increase number of small particles IN THE ORBIT that interferes with the telescope observations (what if exploding it allows the particles to be shoot out so far out into space that it may increase the number of small particles but is now in an orbit that wont interfere with the telescope observations so it doesnt matter that the number increased)
where as with D, we can try to modify all the other factors (i.e. remove debris or explode large satellites) but if the problem remains with the telescope itself, doing all of that is not going to make a difference.

This one is close but I pick E.

because questions is why the idea of exploding is ill conceived..this idea will make problem qouted in D worse but that problem will exist even without this explosion solution.
E is more direct I believe.

One more for E, best choice among the available options.

Responding to a pm:

Problem: Debris interferes with telescope observations but a few large satellites interfere more seriously because of strong reflections.
Solution: Explode the satellites. Since large satellites interfere more seriously, convert them to debris. The interference will be reduced since debris causes less interference.

Question: What is the problem with the solution?
(E) A large increases in the number of small particles will create a blanket of reflections. This will cause serious interference with telescope observations. Makes sense. Correct answer.
(D) Doesn't tell us why it is a bad idea to convert satellites to debris. Just says what you should do if you want to get rid of interference completely. Our plan is to decrease interference and this option doesn't tell us why it will not work. We have to focus on the option that tells us exactly why our plan will not work. Our plan is not to completely get rid of interference but to reduce it. We want to improve the observations. It tells us what we can do to make them perfect. But it doesn't say that we will not be able to improve our observations using our solution.

I agree E is the only solution which points out the problem with the proposal. The argument is awfully wordy. You need to cut the fluff to really get to the crux.

Debris causes little interference, while satellites causes more.

Little interference is not the problem.....so we can live with debris that goes round merrily.

Hence, D is a good solution, but doesn't help with the main issue....kaput satellites!....so D doesn't address the main issue.

They suggest exploding the satellites....which may cause 'more' debris......'less' debris is ok..more debris may cause more interference....hence ill conceived....E says it all.

Hope this helps
