Practice Listening: Multiple Choice, Single Answer ID: #41045 Short Hubble Space

Instructions ›

You will see a video about the technical and operational history of the Hubble Space Telescope. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

The Hubble Space Telescope is an orbiting observatory that was launched in 1990. Ground based observations of the stars are limited because of the blurring effects of the Earth's atmosphere, but because the Hubble telescope is in orbit about 380 miles above the Earth, it can produce sharper images than telescopes on the surface. The Hubble's large primary mirror reflects light from space to a second mirror. The light bounces off this mirror and passes through a hole in the centre of the primary mirror. Special equipment then records the picture, but after the telescope was launched, NASA engineers discovered that the primary mirror was not focusing correctly. In 1993, astronauts in the Space Shuttle were sent to repair the optics, a job that was made easier because the telescope was designed to be repaired in space.

What was the unique design feature of the Hubble Space Telescope that facilitated its repair in 1993?

* Listen to the recording and select the correct answer

The telescope ability to operate without human intervention The telescope being located closer to Earth than other satellites The telescope design allowing for in-space repairs The use of a large primary mirror for clearer images

Option 3: "The telescope design allowing for in-space repair"

Explanation: This option is correct because the text explicitly states that the Hubble Space Telescope was designed to be repaired in space, which facilitated the repair work done by astronauts in 1993. This unique design feature is directly linked to the main idea of the text regarding the telescope's functionality and maintenance.

Option 1: "The telescope ability to operate without human intervention"

Explanation: This option is incorrect because the text does not mention that the Hubble Space Telescope operates without human intervention. In fact, the text highlights the need for human involvement when astronauts were sent to repair the telescope in 1993. Therefore, this statement contradicts the information provided.

Option 2: "The telescope being located closer to Earth than other satellites"

Explanation: This option is incorrect as the text does not state that the Hubble Space Telescope is closer to Earth than other satellites. It mentions that the telescope is 380 miles above the Earth, but it does not compare this distance to other satellites. Thus, this option lacks supporting information from the text.

Option 4: "The use of a large primary mirror for clearer images"

Explanation: This option is incorrect because, while the text mentions the large primary mirror contributing to sharper images, it does not relate this feature to the telescope's repairability. The focus of the question is on the design feature that allowed for repairs, which is not addressed by this option.
