IMO E.

OA is A, which I think is wrong, in A, B and D "venture" is not apropriate with the singular noun 'spacecraft', Anyway, C and E sounds much better using future tense and between C and E also went for E. Does anybody agree that there is something wrong with OA? How often does it happen?

446. It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.
(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

it is A. D and E are wrong for using 'known now'. it should be 'now known'.

B is wrong for using plural verb 'venture'. and C is wrong for 'known as being' and i think 'again' is also mis placed.

Sudeep .. you got me .. sorry didnt see that well. OK I eliminate B for using 'being' ... or wrong modifier. modifier should modify 'mars' so it should be closer to the modifier.

easy to eliminate, huh? :-D

What a tricky question."before" surely doesn't require future tense, as for "spacecraft" didn't know that it could be both countable and uncountable. Thanks for explanation :)

I tend to disagree with the OA. (Please have such a tendency for all questions but those from OG - they are always correct).

Guys remember that being is almost always incorect and almost does not equal to always, I mean being is incorrect in 95-99% of cases, but in 1-5% of cases it is correct.

I am a non-native speaker, so idiom usage is on the most difficult areas for me.
What I do often, when I stuck on unknown idioms I refer to Oxford Dictionary.

In this particular case, I have seen the following:
known ~ sb/sth as sth [usuallypassive] to give sb/sth a particular name or title:
The drug is commonly known as Ecstasy. * Peter Wilson, also known as 'the Tiger'.

So the correct usage of idiom is X is known as Y.
I want to ask native speakers why this idiom is wrong here and what is the correct one.

thanks

C and E which use the correct idiom of "as" have a flaw in that they use "will" --- which conveys certainty of the occurrence of an event in the future

It "may" be another 15 yrs <---> "will" venture --- use of the 2 will/may does not make sense; how can there be certainty that they will leave again for mars when it is not known whether they will take off for sure in 15 yrs time (they've put a "may" in the sentence).

Also note that A does not use "spacecraft" in singular form. Jus coz 's' is missing doesn't mean this word can't be used in plural form. Aircraft, spacecraft etc can be plural even without the 's'; i.e. it is singular and plural: https://en.wiktionary.org/wiki/spacecraft

(A) again venture to Mars, a planet now known to be (precise & clear: future & present tense)
(B) venture to Mars again, a planet now known for being (being – deadly word in GMAT)
(C) will venture to Mars again, a planet now known as being (being – deadly word in GMAT)
(D) venture again to Mars, a planet that is known now to be (venture again sounds awkward and no need to use that as a referrant)
(E) will again venture to Mars, a planet known now as being (being – deadly word in GMAT)

counter arguments welcome instead of kudos

Both Idiom usage is correct - Known to be .. and X known as Y.

Contextually, the intended meaning here was to infer what Mars is known to be to human beings.
Known as usage would be wrong because its used when u want to give an alias of some noun.
Eg - The drug is commonly known as Ecstasy. * Peter Wilson, also known as 'the Tiger'.

Known as vs known to be - MGMAT - Idioms chap.

(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 - redundant known now to be
(E) will again venture to Mars, a planet known now as being

"May" in the non-underlined part makes "will" useless.

Spacecraft and aircraft are both plural; you may refer to the freedictionary.com to verify this. A spacecraft or an aircraft is singular.

Natia!

It's a pretty good question
+1 kudos for you.

I researched on net and found that OA is indeed A.

Following reasons I found. Someone please confirm:

1) 'Before', and other time words like 'after, until, when, as soon as', are not usually followed by future tense.

e.g.,
I'll call you before I cook dinner.
Before I die, I want to do....
Before I'll die. is wrong.

2) spacecraft can be singular and plural. Similar to fish in the monkfish question. ==>justify the usage of venture and not ventures.

Finally Elimination:
It may be another fifteen years before spacecraft from Earth again venture to Mars, a planet now known to be cold, dry, and probably lifeless.
(A) again venture to Mars, a planet now known to be - correct
(B) venture to Mars again, a planet now known for being
- Modifier placement of a planet
(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
- "known now to be" is awkward; "now known to be" is preferred.
(E) will again venture to Mars, a planet known now as being


------
Please correct me wherever I am wrong!


Thanks! ... I was stuck at spacecraft being singular ..

(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

it is A. D and E are wrong for using 'known now'. it should be 'now known'.

B is wrong for using plural verb 'venture'. and C is wrong for 'known as being' and i think 'again' is also mis placed.

In your reasoning, why B is wrong for 'vintage', while A is correct with it?

The part after the comma should be followed immediately after "Mars", and not "again".

I think the meaning approach quickly eliminates 3 highly contested answers, and possibly eliminates the 4th as well.

Mars is not know as or known for being lifeless. It is known for being the planet right after earth, or known for being 1 of the 8 (or 9 for the pluto fans) planets in the solar system. IMO that eliminates B, C, and E.

Between A and D, A barely edges out D. In addition to what was already mentioned about D in the comments, I think there is a slight implication that D conveys: the order of "venture" and "again" in D seems to imply a prior trip would be repeated in the next 15 years. Surely, a subsequent trip would have a new spaceship or a different crew, implying it is a new trip rather than a repeat of a prior trip. That may be a less satisfying explanation for why D is wrong, but fits with the meaning-based approach to POE.

"Spacecraft" is one of those nouns that can be singular or plural.

So, in this context, "spacecraft" is understood to be plural.

We can tell that it must be plural because it's not preceded by "a" or "the."
