Practice Listening: Multiple Choice, Single Answer ID: #41034 Short Dinosaurs

Instructions ›

You will see a video about the evolutionary comparison of dinosaurs and birds. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Most scientists believe that birds descended from certain kinds of small meat-eating dinosaurs. These dinosaurs had bodies that resembled birds in certain ways. Such similarities included an S-shaped curve of the neck, a furcula or wishbone in the breast, and a foot composed of three primary toes with the 4th toe on the back of the foot. Some scholars believe these dinosaurs may have developed feathers. The feathers could have been used to keep their bodies warm-blooded. Scientists have also found skeletons of dinosaurs sitting on top of their egg nests in a bird-like position. The fossils suggest that dinosaurs may have cared for their young in much the same way as birds do. Over millions of years, these small dinosaurs may have developed into modern birds.

Option 4: "Feathers"

Explanation: The text states that some scholars believe these dinosaurs may have developed feathers, which could have been used to keep their bodies warm-blooded. This directly addresses the question about maintaining warm-bloodedness, making this option the correct answer.

Option 1: "The S-shaped curve of the neck"

Explanation: The text mentions the S-shaped curve of the neck as a similarity between birds and certain dinosaurs, but it does not indicate that this feature was used for maintaining warm-bloodedness. Therefore, this option does not align with the main idea of the text regarding warm-bloodedness.

Option 2: "The furcula or wishbone in the breast"

Explanation: While the text describes the furcula or wishbone as a feature of these dinosaurs, it does not connect this feature to the maintenance of warm-bloodedness. Thus, this option is not supported by the text.

Option 3: "The foot composed of three primary toes"

Explanation: The text discusses the structure of the foot but does not mention it in relation to warm-bloodedness. This option lacks the necessary support from the text to be considered correct.
