Practice Reading: Multiple Choice, Single Answer ID: #33828 Platypus
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
The platypus sleeps during the day and moves mostly at night. It is a very good swimmer and spends much of its time in the water. The toes on its feet are joined. When it swims, it pushes itself along by moving the front two feet. The tail and back feet help it to turn left or right but do not make it faster. The platypus eats other animals. It eats worms, insect larvae, shrimps, and yabbies, which are a kind of freshwater crayfish. It digs these animals out of the bottom of the river with its beak or catches them while swimming. Its nose can sense many things that other noses cannot. The platypus can sense electricity from other animals. It keeps its eyes shut when swimming, using only its other senses, such as hearing, touch, and changes in the electrical field. The platypus can also hunt without using its eyes. These are adaptations to life in rivers where the water is opaque with sediment.

Option 4: "The water is murky."

Explanation: The text clearly states that the platypus keeps its eyes shut when swimming because the water is opaque with sediment. This directly supports the idea that murky water is the reason for closing their eyes, allowing them to rely on other senses.

Option 1: "Something might get in their eyes."

Explanation: This option suggests a general concern about debris entering the eyes, but the text does not mention this as a reason for the platypus closing its eyes. The focus of the text is on the adaptations of the platypus for swimming in murky water, not on potential eye irritation.

Option 2: "It helps them to relax."

Explanation: While closing eyes can be associated with relaxation, the text does not support this idea. Instead, it emphasizes the necessity of closing their eyes to rely on other senses while swimming, particularly in murky water.

Option 3: "It helps them to concentrate on what they’re doing."

Explanation: This option implies that closing their eyes aids in concentration, but the text specifically states that the platypus closes its eyes to use its other senses, such as hearing and touch, rather than for concentration.
