Is this sentence correct as 'did' tries to substitute 'has' (when 'has' is a helping verb)?

Hi Skywalker18, in this sentence, did is not substituting for has; did is substituting for the present perfect tense has gone (present perfect of action verb go).

An official example that comes to mind:

Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to 1950.

I am a bit confused here...Generis points that "2) The verbs do/does/did cannot substitute for have (has, had, etc.) when have is a helping verb." An example to this is "Wrong: Gaurav has eaten all his supper, but GMATNinja did notHAS NOT.

However as Aisle pointed official example shows that did in fact has referred to " has grown"

The statement in red is incorrect.

In the sentence above, did is standing in for the simple past tense form of has gone.

Hi Mitch, greetings! This is what I wanted to suggest as well (as is clear in the subsequent official example that I cited). Perhaps it didn't come out that way :|

did is (the past tense that is) substituting for the present perfect tense has gone (present perfect of action verb go) and not for has.

Since then several thousand such ''quasi-stellar radio sources,'' or quasars, have been discovered. Assuming the yardstick used to measure cosmic distances - the so-called red shift - is valid, many quasars are so far away their light has taken billions of years to reach the Earth. They are therefore seen as they were during the infancy of the universe and may be galaxies in an early, extremely brilliant stage of development.


In this OG question how to eliminate option C? AndrewN

Hi Experts, MartyTargetTestPrep, AndrewN

In option D, the verb "did" is used as the past tense of the verb "appear", which is used earlier in the sentence. Thus the option becomes "they appear to us as they appeared in the formation of the universe." The only error I can spot in this sentence is the preposition "in" instead of "during".

How can we interpret the "to us" part after the second verb "did" (appeared). As per the explanations above in this post, option D is incorrect because "the way Quasers appear to us now is the same as they appeared to us when the Universe was formed. But, when the Universe was formed, we did not exist."

Thank You

A —> pronouns and verb tense look good
B —> b uses the wrong tense, as past perfect is used only for compound past actions. Here, only one action in the past
C —> we did not see any quasar during the formation of the universe, as their light did not reach the earth yet. Wrong in meaning
D —> Quasars did not appear to us in the formation of the universe at all; thus, the wrong meaning
E —> same meaning mistake here
