OFFICIAL EXPLANATION



On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, and pointed to future possibilities for documenting the planet from outer space.

(A) and pointed

Incorrect.

This answer choice is illogical. While the parallel construction A and B (were taken and pointed) is grammatically correct, as both are verbs in the past tense, it creates an illogical sentence, stating that it was the the first black-and-white images of earth which pointed to future possibilities [...].

This question requires finding a logical subject for the verb to point. What could point to future possibilities? Logically, none of the nouns in the first clauses can. It does not make sense to say that the first black-and-white images of earth, or a motion-picture camera, or a V-2 missile, or the New Mexico desert points to future possibilities.

Rather, the entire situation, the fact that the pictures were taken from space is what points to future possibilities.

Look for an answer choice with a verb form that more correctly expresses the logic of the sentence.



(B) and it pointed

Incorrect.

While this answer choice corrects the logical issue in the original sentence, by introducing a new subject in the second clause (it), it is stylistically flawed.

The pronoun it is ambiguous because it can refer to at least two singular nouns in the preceding part of the sentence (camera, missile), although none of these references actually makes sense.



(C) and points

Incorrect.

This answer choice is grammatically incorrect. The plural X of Y subject the first black-and-white images of earth is followed by a parallel construction of two verbs: were taken and points. However, points is a singular verb which does not agree with the subject.

What helps us identify this question as a Subject Verb Agreement question is the following Stop Sign: an X of Y subject, A long, complex subject or a great distance between subject and verb



(D) pointing

This answer choice corrects the logical issue in the original sentence, by changing the conjugated verb and pointed to the non-conjugated V+ing (or participle) form pointing.

The phrase "pointing to future possibilities for documenting the planet from outer space" correctly describes the entire situation, as it was not the images themselves but the fact they were taken that pointed to future possibilities.



(E) and it points

Incorrect..

While this answer choice corrects the logical issue in the original sentence, by introducing a new subject in the second clause (it), it is grammatically incorrect and stylistically flawed.

Using the Present Simple verb points after a Past Simple verb were taken and the past time phrase On October 24, 1946 violates the Once in the Past, Always in the Past rule, and is therefore grammatically incorrect.

In addition, the pronoun it is ambiguous because it can refer to at least two singular nouns in the preceding part of the sentence (camera, missile).

I settled on D as the right answer.

The biggest clue to solve this question is to focus on the meaning of the sentence. When you do so, you will realize that the latter part of the sentence and pointed to future possibilities for documenting the planet from outer space seeks to present the result of the the event that took place on October 24, 1946. Since it makes sense to say that images of earth taken from a motion picture point to future possibilities for documenting the planet from outer space, D is correct.

Quote:
(A) On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, and pointed to future possibilities for documenting the planet from outer space.

a comma preceding and implies that what follows and must be a full independent clause. However, pointed to future possibilities for documenting the planet from outer space is a participial phrase and not a clause. Eliminate A for this error.

Quote:
(B) On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, and it pointed to future possibilities for documenting the planet from outer space.

Logically it must refer to the subject of the previous clause, which is images. As we can see, the pronoun it does not agree in number with images. Eliminate B for pronoun error.

Quote:
(C) On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, and points to future possibilities for documenting the planet from outer space.

As explained for option A above, points to future possibilities for documenting the planet from outer space should be a clause instead of a phrase. Eliminate C for this error.

Quote:
(D) On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, pointing to future possibilities for documenting the planet from outer space.

Correct as per the explanation given above. Pointing to future possibilities for documenting the planet from outer space presents the results of the previous clause. In addition, pointing makes sense with the subject of the sentence, images of the earth.

Quote:
(E) On October 24, 1946, the first black-and-white images of earth were taken from a motion-picture camera mounted on a V-2 missile launched from the New Mexico desert to an altitude of 65 miles, and it points to future possibilities for documenting the planet from outer space.

Just as in B, In E, there is a pronoun error. it does not have a logical antecedent. E can be eliminated for this error.

The correct answer is D. I would call it a 600-700 level question

The solution lies in the meaning. Grammatically, other options might also seem right but once we understand the meaning, we know that the second part is a result of the first part.

(A) and pointed : The second part is more qualitative and the whole sentence read together doesn't make sense.

(B) and it pointed :It solves the issue in the first part but "it" is ambiguous.

(C) and points : Again the same issue and the tense issue is introduced here

(D) pointing : Correct

(E) and it points : Same issue as B
