Some paleontologists have suggested that Apatosaurus, a huge dinosaur, was able to gallop. This, however, is unlikely, because galloping would probably have broken Apatosaurus’s legs. Experiments with modern bones show how much strain they can withstand before breaking. By taking into account the diameter and density of Apatosaurus leg bones, it is possible to calculate that those bones could not have withstood the strains of galloping.

Which one of the following most accurately expresses the conclusion drawn by the argument as a whole?


(A) Galloping would probably have broken the legs of Apatosaurus.

(B) It is possible to calculate that Apatosaurus leg bones could not have withstood the strain of galloping.

(C) The claim of paleontologists that Apatosaurus was able to gallop is likely to be incorrect.

(D) If galloping would have broken the legs of Apatosaurus, then Apatosaurus was probably unable to gallop.

(E) Modern bones are quite similar in structure and physical properties to the bones of Apatosaurus.

Option C: it is the correct option that defines conclusion of the statement.

The conclusion for the statement is that some of the paleontologists who have suggested the Apatosaurus to be able to gallop is unlikely. Therefore, this option completely defines that incorrect suggestion.

The other options are out of context.


Kindly give kudos if you agree or like the explanation! :)

Which one of the following most accurately expresses the conclusion drawn by the argument as a whole?


Paleontologists : X Dinosaur was able to gallop.

Author : Negative. If X would have galloped, his legs would have been broken.

(This is the main point that author wants to make. We want to build our conclusion on Author's view and not on the view of Paleontologists. Let us go to options and use "Therefore" before every answer choice.


(A) Therefore, Galloping would probably have broken the legs of Apatosaurus.

Incorrect : Author's view is X never galloped. If X would have galloped, then his legs would have been broken.

(B) Therefore, It is possible to calculate that Apatosaurus leg bones could not have withstood the strain of galloping.

Incorrect : Not the main point we want to discuss. It can be an assumption but no the conclusion.

(C) Therefore, The claim of paleontologists that Apatosaurus was able to gallop is likely to be incorrect.

Correct : As we discussed above.

(D) Therefore, If galloping would have broken the legs of Apatosaurus, then Apatosaurus was probably unable to gallop.

Incorrect : Different from Author's view and can't be the conclusion.

(E) Therefore, Modern bones are quite similar in structure and physical properties to the bones of Apatosaurus.

Incorrect. It can be an assumption to prove the fact the calculations can be done properly as two type of bones are quite similar, but it can not be a conclusion.

Hi I have 3 doubts:
Choices A,B and C repeat the informations already mentioned in the argument. But option D states something that can be inferred reading between the lines..So why is (1) D incorrect?;(2) only C correct but not A or B and (3) what are the differences between "Inference", "Conclusion" ,"Main point" and "Must be true" type questions?

Looking forward to your thoughtful insights...
Thanks in advance
