1st, 2nd, and 3rd.
The first statement paraphrases the claim that the
gods act “within certain boundaries,” while the second statement paraphrases
the claim that they do so “to accomplish his or her own agenda.” The third
statement is the main point of the passage: that the gods act as agents of
destiny, which they do not themselves control.

(C).
Chemical blockers scatter, or disperse, light waves. Chemical
absorbers use light waves to promote electrons which then release light waves
with a longer wavelength as they return to their ground energy state. Thus,
choice (C) is correct. Choice (A) makes a reference to lightening and
darkening light waves, neither of which is mentioned in the passage. Choices
(B) and (D) refer to converting light waves to radiation, which is not
mentioned in the passage. And absorbers absorb the radiation into their
molecular structure, not into the skin as in choice (E).

(D).
The chromophores absorb light in the 290–320 nm range and use it
to promote (or move up) electrons between energy levels. Since light with
wavelengths of 300 nm falls in this range, their electrons should move up in
energy levels when exposed to it. Thus, choice (D) is correct. In choice (E),
the phrase “they will promote the discrete quantal amounts of energy
required” is unjustified, as it is the
electrons
that get promoted, not the
discrete quantal amounts of energy required. The discrete quantal amounts of
energy simply establish the wavelength range that the chromophores will
absorb. Choice (C) would be correct if not for the range given: the author
does not indicate how chromophores react to light above 320 nm. Choice (B)
is the exact opposite of what the question asks for. Choice (A) applies to
physical blockers but not to chemical absorbers.
