In option D: "The tracks that dinosaurs left show that they walked with their feet directly under their bodies, as do mammals & birds". I am not able to get how to complete the second part of the sentence.
Like if the option was "The tracks that dinosaurs left show that they walked with their feet directly under their bodies, as mammals & birds do". Then it would be clear that "The tracks that dinosaurs left show that they walked with their feet directly under their bodies, as mammals & birds do walk with their feet directly under their bodies.".
But in option D I am not able to complete the sentence. Secondly what difference does it make when "do" is used before versus after?
please clarify
Due Regards

(D) The tracks that dinosaurs left show that they walked with their feet directly under their bodies, as do mammals and birds, not extended out to the side in the manner of modern reptiles.
Why isn't the 'they' ambiguous here? Can it not refer to both, the tracks or the dinosaurs? Which additional condition should prevail for us to eliminate an option because of an ambiguous pronoun?

Dear Friends,
Here is a detailed explanation to this question-
Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that the tracks left by dinosaurs indicate that they walked with their feet directly under their bodies, in the same way, that mammals and birds do.
Concepts tested here: Meaning + Pronouns + Tenses + Comparisons
• A comparison must always be made between similar things.
• Information that is permanent in nature is best conveyed through the simple present tense.
• The simple past tense is used to refer to actions that concluded in the past.
A:
1/ This answer choice alters the meaning of the sentence through the cause "Dinosaur tracks show them walking"; the construction of this clause illogically suggests that the tracks visually depict dinosaurs walking with their feet directly under their bodies; the intended meaning is that the tracks indicate the fact that dinosaurs walked with their feet directly under their bodies.
2/ Option A suffers from a pronoun error, as the pronouns "them" and "their" lack a clear and logical referent.
3/ Option A incorrectly compares the verb phrase "walking with their feet directly under their bodies" to the noun phrase "mammals and birds"; remember, a comparison must always be made between similar things.
B: Trap.
1/ This answer choice suffers from a pronoun error, as the pronouns "they" and "their" lack a clear and logical referent.
C:
1/ This answer choice alters the meaning of the sentence through the phrase "tracks that showed them walking"; the construction of this clause illogically suggests that the tracks visually depicted dinosaurs walking with their feet directly under their bodies; the intended meaning is that the tracks indicate the fact that dinosaurs walked with their feet directly under their bodies.
2/ Option C incorrectly uses the simple past tense verb "showed" to refer to information that is permanent in nature; remember, information that is permanent in nature is best conveyed through the simple present tense, and the simple past tense is used to refer to actions that concluded in the past.
3/ Option C incorrectly compares the verb phrase "walking with their feet directly under their bodies" to the noun phrase "mammals and birds"; remember, a comparison must always be made between similar things.
D: Correct.
1/ This answer choice uses the phrase "show that they walked", conveying the intended meaning - that the tracks indicate the fact that dinosaurs walked with their feet directly under their bodies.
2/ Option D avoids the pronoun error seen in Options A and B, as the pronouns "they" and "their" clearly and logically refer to the noun "dinosaurs".
3/ Option D correctly uses the simple present tense verb "show" to refer to information that is permanent in nature.
4/ Option D correctly compares the verb phrases "walked with their feet directly under their bodies" and "do mammals and birds".
E:
1/ This answer choice alters the meaning of the sentence through the cause "dinosaurs are shown walking"; the construction of this clause illogically suggests that the tracks visually depict dinosaurs walking with their feet directly under their bodies; the intended meaning is that the tracks indicate the fact that dinosaurs walked with their feet directly under their bodies.
2/ Option E incorrectly compares the verb phrase "walking with their feet under their bodies" to the noun phrase "mammals and birds"; remember, a comparison must always be made between similar things.
Hence, D is the best answer choice.
