A - what's wrong with the sentence? in D the part - "to be sighted was observed " seems not quite right.

What I got:
Q1 - D
Q2 - A

------
Question 1
You have two past events here, one which occurred before the other.

This is a case of Past Perfect Tense

The correct usage is [HAD] + Past Participle for the earlier event, and the simple past tense of the verb that modifies the later event.

Answer A uses "had" to identify the later event, which is incorrect.

Modifiers

In choice B, the logical modifier is "the discovery", since the discovery was not announced until February 1968.

In choice C, the "pulsar" was observed by Jocelyn Bell in 1967, not the disscovery.

While

While should be used when an event is going on concurrently with another event.

Answer choice E states that the announcement and the observation occurred at the same time.

Answer D is the correct choice.

------
Question 2:
Comparisons:
The writing of the Aztecs is being compared to the writing of the Mayas.

Choice B compares the writing of the Aztecs to the Mayan people. Incorrect.

Choice C is missing an "it". Take out the appositive and you get

.During the same period in which the Maya were developing a heiroglphic system of writing, the Aztec people also developed a written language, but was more pictographic in nature.

Idiomatic

"Not".. should be followed by "but"...

D and E don't follow this structure. You can eliminate them.

The other thing I noticed is that choices B, C, D and E seem to attribute the disparity in language sophistication between the Aztecs and the Mayan to the Aztec's language being more pictographic in nature.

The Mayan's language, however, was hieroglyphics, which is pictographic by definition. Are we to assume that there is an inverse relationship between the pictographic nature of a language and its level of sophistication?

I'm not sure if that judgement call can be made in a SC question.
