OE
Blank (i) calls for a description of insects that predators would generally avoid. “Noxious,” meaning harmful, is the correct answer; there is no reason to suspect that predators would avoid nutritious or rare prey. Blank (ii) characterizes the lizards’ initial response to beetles they eventually ate, and since it is followed by a clause beginning with “because,” the lizards’ response must be explained by the beetles’ irritant-spraying behavior. “Rejected” fts these criteria; animals routinely avoid unpleasant stimuli. “Sought” is incorrect because it is unlikely that lizards would seek out prey with such defensive behavior, and “resembled” is incorrect because nothing else in the passage suggests that the described behavior is shared by the lizards. Finally, the author states that eating the beetles apparently did not harm the lizards; the “since” of the last sentence introduces the evidence on which this observation is based. Tus Blank (iii) must be flled by a word that suggests the lizards were unharmed. “Erratic” or “laborious” postmeal locomotion might indicate otherwise; therefore the correct answer for Blank (iii) is “nonchalantly.”
Thus the correct answer is noxious (Choice C), rejected (Choice E), and nonchalantly (Choice I).
