Question

the brown recluse is one of the toxic venomous spiders found in the united states. like all spiders, it has eight legs and two body parts. however, as its name indicates, it is timid and reclusive. active at night when it searches for prey, as do other nocturnal spiders, it retreats to dim, secluded areas during the day. two distinguishing features of this spider make it easy to identify. the first is a dark violin - shaped marking on the upper body of adults, which explains why it may also be called a fiddleback spider. it also has six eyes—the majority of spiders have eight—that are visible under magnification. while the brown recluse is not aggressive, it can unintentionally wander into clothing or bedding and bite people in defense. fortunately, though feared by many, brown recluse bites are rare and have never been proven to have caused any human deaths. according to the passage, two distinguishing features of a brown recluse spider are a two body parts and eight legs. b magnifying vision and eight eyes. c nocturnal and aggressive behaviors. d violin - shaped marking and six eyes.

Explanation:

The passage states that two distinguishing features of the brown recluse spider are a dark violin - shaped marking on the upper body of adults and six eyes (while most spiders have eight). Option A: two body parts and eight legs are features of all spiders, not distinguishing features of the brown recluse. Option B: the spider has six eyes, not eight, and there is no mention of magnifying vision in the context of the spider's features. Option C: the spider is not aggressive (the passage says "not aggressive"), so this option is incorrect. Option D matches the two distinguishing features described in the passage.

Answer:

D. violin - shaped marking and six eyes.
