Answer:
A). Invisible ink isn’t really invisible at all.
Explanation:
The chief idea which the author aims to convey through the given passage would be that '<u>invisible ink is not actually invisible</u>.' This claim is substantiated through the descriptions asserting the type of inks(lemon juice, brown ink) that have been used to write such invisible content and also regarding how this invisible content can be visible(by holding the paper over candle's flame or using a chemical). This shows that the ink is not actually concealed completely. Thus, <u>option A</u> is the correct answer.

Answer: Inactive.
Explanation:
The meaning of the word 'inert' is 'not moving'. In the excerpt, it is described that the machines were not moving, as if they were dead. The word 'inactive' has the same meaning - it stands for something that is not operating, moving or is out of function. This is why we could replace 'inert' with 'inactive' in this example.
