IMO E, evident by para 3.

You may have been tricked by C and D which are close
C is defied by line 1 of last para and D is incorrect since there was one incident of decreasing whereas D mentions a trend

@PATANJALI

Passage suggests "less well known..." ALSO it says "70000 other small bodies, primarily found in K-belt.."
never does passage concretely defines 70000 as K Belt Objects or does states any relation thereby.

Basically nothing in the passage supports option C.

In last 2 lines of para 1, Passage at least 70000 bodies are found in K-Belt and then it categorizes KBO's. In 1st line of last para, passage says K-belt is NOW much smaller than it was. So "at least 70000 figure" may have been reduced to (say) "at least 50000". We do not have any info to identify the at least ____ , we only know that number is reduced.

We can take small bodies found in K-belt as KBO's

According to the passage, which of the following can be inferred about Kuiper Belt Objects?
a) they orbit between Neptune and Pluto ( NO, the para also says that Pluto and these KBO are little Plutos)
b) they are all affected by the presence of Neptune ( NO, in 3rd para it says so - occasional proximity can send them out of solar system entirely. It means not all but only some )
c) at least 70,000 of them are known to exist ( Yes, 1st para says so)
d) the number of them is decreasing ( NO, nowhere this is mentioned)
e) some of them travel beyond the solar system ( Yes, this is mentioned)

My confusion is between C and E....can any please tell me if i am on the right track here?

So "at least 70000 figure" may have been reduced to (say) "at least 50000". We do not have any info to identify the at least ____ , we only know that number is reduced.
1st para: LESS well known is the existence of at least 70,000 other small objects orbiting the sun beyond Neptune. These objects are primarily found within Kuiper Belt (NOTE: the use of PRESENT TENSE - this shows minimum of 70,000 objects exist today)

Last para: The Kuiper Belt is actually much smaller than it once was - THE REDUCTION YOU MENTIONED IS with respect to sometime in PAST. The numbers have reduced to atleast 70,000 from an unknown numbers (definitely higher) in the past.

IMO what goes against C is that 'pssg never says whether 70,000 other small objects are actually KBOs"

It seems that words "less well known is the existence..." are tying to imply to there is less confidence over statement following it.

Those objects are "at least 70000" are certainly K-belt objects. See last line of 1st para "these objects primarily are found in a ring known as K-belt"

In my opinion (E)as 3rd para specifically says that the objects in question are thrown out of solar system...
