Question

part a
which of the following best summarizes the entire article?
a there are more than 36,000 different kinds of spiders. some of them catch their food
with a web, such as the garden spider with its orb web. others, like the wolf spider, just
jump on their prey, bite it, and then eat it.
b spiders may resemble insects, but they are actually arachnids, which is a different class
of animal. arachnids have eight legs instead of six, as insects do. other arachnids include
scorpions, ticks, and daddy longlegs.
c from mountain peaks to deserts to caves, the spider is found almost everywhere.
wherever spiders go, they help humans by controlling the insect population through
hunting. since spiders don’t have teeth, they dissolve their prey by spitting digestive
juices on it.
d spiders are predators in a group of animals called arachnids. more than half of all spiders
catch prey by building webs from silk they spin themselves. most spiders are harmless
to humans, who actually benefit from the pest control provided by these insect - eating
creatures.

Explanation:

Option A only mentions different kinds of spiders and their web - related hunting. Option B focuses on the classification of spiders as arachnids and other arachnids. Option C emphasizes where spiders are found and how they help humans in a limited way (controlling insect population through hunting). Option D comprehensively covers that spiders are predators (in the arachnid group), how most catch prey (web - building), their harmless nature to humans, and the benefit (pest control) humans get from them.

Answer:

D. Spiders are predators in a group of animals called arachnids. More than half of all spiders catch prey by building webs from silk they spin themselves. Most spiders are harmless to humans, who actually benefit from the pest control provided by these insect - eating creatures.
