"Another possible defense against rhinoviruses was proposed by Rossman, who described rhinoviruses’ detailed molecular structure. Rossman showed oar that protein sequences common to all rhinovirus strains lie at the base of a deep “canyon” scoring each face of the capsid. The narrow opening of this canyon possibly prevents the relatively large antibody molecules from binding to the common sequence, but smaller molecules might reach it. Among these smaller, nonantibody molecules, some might bind to the common sequence, lock the nucleic acid in its coat, and thereby prevent the virus from reproducing. "
It can be inferred from the passage that the protein sequences of the capsid that vary most among strains of rhinovirus are those

(A) at the base of the “canyon”
(B) outside of the “canyon”
(C) responsible for producing nucleic acid
(D) responsible for preventing the formation of delta-receptors
(E) preventing the capsid from releasing its nucleic acid

Question: Greg immediately scans the protein sequence and read that sentence and answer the question, everything is great and I understood, but here is my problem,

I do not feel confident as if the one line was enough or I should read next 2 lines as well just to ensure , if not any other things are mentioned in the paragraph about protein sequences as they could ve written in pronoun so might not look obvious unless I read them so @gregmat how do you get out this dilemma, In few questions I feel I do not get what I needed and read a bit further for example, here I thought oh this can not be that simple, may be some more details they have mentioned about protein sequence and read the next few lines , this consumes my time

The passage suggests that the protein sequences of the capsid that vary most among strains of rhinovirus are those outside of the “canyon” (Option B). The “canyon” is described as having protein sequences common to all rhinovirus strains, implying that the varying sequences are located elsewhere on the capsid.

Regarding your concern about whether to read further or not, it’s a balance. On one hand, you want to be efficient and not spend unnecessary time reading information that might not be relevant. On the other hand, you want to make sure you’re not missing any important details. A good strategy might be to first try answering the question with the information you have. If you feel confident in your answer, move on. If not, then consider reading a bit further for clarification. Remember, practice will help improve your ability to make this judgment quickly and accurately.

Personally , I think the thing with Greg is that he always uses these strategies, whether it’s for teaching in class, tutoring, or while taking the official GRE. Thus, he has full confidence in them because he applies them on a daily basis. However, since you’re new to them, there is always some doubt. That’s why Greg recommends some untimed practice with the Big Book so that you can build familiarity with the strategies being taught and figure out when to use them.
