Answers and Explanations
1) A
nocturnal (adjective): active by night, happening during the night.
diurnal (adjective): active by day, happening during the day.
In paragraph 1 the author writes, "Owls are nocturnal. This means that they sleep all day and stay awake at night." If
diurnal is the opposite of nocturnal, then a diurnal animal would sleep all night and stay awake during the day. Choice (A)
is correct. The passage does not provide information to support choices (B), (C), and (D). Therefore they are incorrect.
2) B
In paragraph 2 we learn that "Owls have very large eyes. These eyes absorb more light than normal. Since there is little
light during the night, it is helpful to be able to absorb more of it." Using this information, we can understand that an animal
that has small eyes has trouble seeing in the dark. This is because small eyes are able to absorb less light than large
ones. Choice (B) is correct. (A) is incorrect because animals like mice do not have large eyes. Nonetheless, they are
nocturnal. They are still able to find food in the dark using their sense of smell. (C) is incorrect because small eyes do not
absorb as much light, making it harder to see at night. Therefore an animal with small eyes probably does not see well at
night. If an animal has small eyes, this does not necessarily mean that it is likely to be eaten by an owl. After all, many
animals that have small eyes (like fish, birds, etc.) are not likely to be eaten by an owl. Therefore choice (D) is incorrect.
3) B
In paragraph 2 we learn that "Owls have very large eyes." This helps them "find food in the dark." This supports option (I).
In paragraph 3 we learn that "Owls also have very good hearing." This helps them "catch their prey even when it is very
dark." This supports option (II). In paragraph 4 we learn that "Like owls, mice are also nocturnal animals. Mice have an
excellent sense of smell." This helps them "find food in the dark." However, the question asks about owls, not mice. The
passage does not provide information to support the idea that owls can find food in the dark using their sense of smell.
This eliminates option (III). Therefore (B) is correct.
4) C
prey (noun): an animal that is hunted by other animals.
To answer this question correctly, it helps to use context. In paragraph 2, the author writes that the owl's large eyes helps
it “find food in the dark.” In paragraph 3, the author gives more information about how owls find food in the dark. The
author says that an owl's sense of hearing helps it to hear “small animals” moving around in the night. This hearing “helps
owls catch their prey even when it is very dark.” Owls have to find food in the dark. This food is the “small animals” moving
beneath them. Owls use their eyesight and hearing to catch their prey, which is another word for an animal that is hunted
by other animals. Choice (C) is correct. The passage does not provide information to support choice (A). Therefore, it is
incorrect. Although the passage does say that the owl hunts "small animals," this does not necessary mean that only
small animals are prey. Small animals are the prey of owls, but not necessarily of other animals. The prey of a lion, for
example, could be a large animal, such as an elephant. Therefore (B) is incorrect. (D) is incorrect because this defines a
predator, which is the opposite of prey.
5) B
In the final paragraph, the author writes: “Being nocturnal helps mice to hide from the many different animals that want to
eat them.” In other words, sleeping during the day helps mice to keep themselves safe. This means choice (B) is correct.
The passage does not provide information to support choices (A), (C),and (D). Therefore they are incorrect.
6) A
In the final paragraph, the author writes: “Being nocturnal helps mice to hide from the many different animals that want to
eat them. Most of the birds, snakes, and lizards that like to eat mice sleep at night—except, of course, owls!” Because
mice are nocturnal, they can hide from most animals that sleep at night. Owls, however, do not sleep at night. For this
reason, it is likely that owls hunt mice. This means (A) is correct. (B) is incorrect because mice cannot hide from owls
because, like mice, owls are awake during the night. The owls can use their excellent senses of sight and sound to find
the mice. Although the author says that mice hide from birds, snakes, and lizards, this does not necessarily mean an owl
needs to hide from these animals as well. After all, an owl is not likely to be eaten by a snake or a lizard. This means (C)
is incorrect. The passage does not provide information to support choice (D). Therefore it is incorrect.
7) D
A good conclusion restates the main ideas or points of the passage. In paragraph 1, the author introduces the fact that
some animals are nocturnal. In paragraphs 2 and 3, the author describes how the owl is nocturnal, and uses its senses to
find food at night. In paragraphs 4 and 5, the author describes another nocturnal animal, the mouse, and how it uses its
senses to find food at night. Using this information, it can be understood that (D) provides the best conclusion because it
accurately restates the main ideas or points of the passage. Although the passage discusses owls, it also talks about
mice. The conclusion in (A) fails to mention this, and is therefore incorrect. Although the passage discusses mice, this is
not the main idea. Rather, this is used as an example of another animal (in addition to the owl) that is nocturnal, and how
that animal uses its sense to find food in the dark. Therefore (B) is incorrect. While the passage does say that both mice
and owls are nocturnal, it does not conclude that this makes them especially vulnerable to attack from diurnal animals. In
fact, the final paragraph contains information that states the opposite: "Being nocturnal helps mice to hide from the many
different animals that want to eat them." This means (C) is incorrect.
