The sentence is checking for noun modifiers .

"a planet now known to be" should modify the noun MARS .

As per the noun modifier rule the modifier should touch the thing it is modifying .

So we can eliminate B and C .

Between TO BE and AS BEING go with TO BE as BEING is mostly considered wrong in GMAT but not always unless we have a better option in this case we do . So eliminate E .

If you compare A and D

A) again venture to Mars, a planet now known to be

D) venture again to Mars, a planet that is known now to be

Both are correct grammatically but (A) is concise as compared to D .

So go for A .

I'm confused ......


Spacecrafts venture....

But,

Spacecraft ventures...


Is spacecraft plural?

Spacecraft is a collective noun
+ its countable 1 spacecraft 2 spacecraft....

If it had been "a spacecraft" it would have been ventures

ok.

then tell me one thing,

army attacks .....

or

army attack .....


FYI, collective nouns will take a singular verb.

By the way, take the help of God Google and search for spacecrafts. You might then want to make some modifications in the question above.

It can either be singular or plural depends on the context..

Eg
Sri Lankan Army attack killing more than 2000 Tamils .


Sudan army attacks press report alleging it raided into Kenya

Both are correct.

Both are correct.

first, I think spacecraft is singular and spacecrafts is its plural. Hence, ventures should accompany spacecraft. You can make it singular, if you use will in the sentence.

hence, my options boil down to C & E.

From them, I will pick C because I think now known is correct.

my reasoning may / may not be correct ...... let's see what the other people say.

may be this will help you

thanks! I was going to PM Ron on this one.

so... I guess, I would have lost some points, had this sort of question come in my real test.

Now I won't!

How is Spacecraft a collective noun? is an Aeroplane a collective noun?

I ruled A out because of Subject verb agreement.

that's what I thought initially. Look at the link given by Anial which has comments by Ron. It will get clear.

Ron's explanation. Now that's bullying.

Spacecraft is Plural.. why..well that's how English gods wanted it to be. Point noted.


A spacecraft is .. singular...

Spacecraft without an article is plural.. what a rip off

agree... ... what can we do.

I agree with you guys , thanks Harsha for bringing this up I havent noticed the subject verb agreement .

Good point .

(A) again venture to Mars, a planet now known to be
(B) venture to Mars again, a planet now known for being
(C) will venture to Mars again, a planet now known as being
(D) venture again to Mars, a planet that is known now to be
(E) will again venture to Mars, a planet known now as being

Hey guys, here's how I solved the problem:

I first immediately eliminated D and E, because, if I'm not mistaken, 'known now' vs 'now known' actually changes the meaning of the sentence.

"now known" = fact is now widely known by all
"known now" = fact was just recently discovered

From there, I was able to eliminate B and C, because a planet isn't a person with feelings. It is an object. Objects aren't known 'for being' anything... A sphere isn't known 'for being' round, it is known 'to be' round. Johnny, on the other hand, is known 'for being' happy, although I guess he could be known 'to be' happy as well.

With that said, I don't know the exact grammar rule for this, sorry.

After eliminating all other choices I was left with A.
