Hello Everyone,
I hope you all are doing awesome with the preparation for the GRE.
I just need some help with the two questions that I’ve given below. If this question has already been discussed before in this forums, please provide me the link if possible
So here is the 3-para passage from the GRE Big Book (pg. 31). If you are finding this difficult to read, I apologize for that cause I could only able to upload 1 image. You can refer to this question from this link:

So there are 7 questions for it, could able to answer 5 of them but finding it difficult to justify the answer for the answer for the following two questions:
So here are the questions. I just need some help in justifying those answers
- It can be inferred from the passage that Chinese observations of the Sun during the late seventeenth and early eighteenth centuries
- A are ambiguous because most sunspots cannot be seen with the naked eye
- B probably were made under the same weather conditions as those made in Europe
- C are more reliable than European observations made during this period
- D record some sunspot activity during this period
- E have been employed by scientists seeking to argue that a change in solar activity occurred during this period
- It can be inferred from the passage that studies attempting to use tree-ring thickness to locate possible links between solar periodicity and terrestrial climate are based on which of the following assumptions?
- A The solar-activity cycle existed in its present form during the time period in which the tree rings grew.
- B The biological mechanisms causing tree growth are unaffected by short-term weather patterns.
- C Average tree-ring thickness varies from species to species.
- D Tree-ring thicknesses reflect changes in terrestrial climate.
- E Both terrestrial climate and the solar-activity cycle randomly affect tree-ring thickness.
