Difficulty: EasyRhetorical Synthesis: Comparison and Contrast

During a study of modern astronomical instruments, a student compiled the following notes:

* The Hubble Space Telescope was launched in 1990 and primarily observes visible and ultraviolet light.
* The Spitzer Space Telescope was launched in 2003 and designed to detect infrared radiation.
* The James Webb Space Telescope was launched in 2021 and also detects infrared radiation.
* Unlike the Hubble Space Telescope, both the Spitzer and James Webb telescopes require specialized cooling systems to function.

The student wants to compare the type of light detected by the Spitzer Space Telescope and the James Webb Space Telescope. Which choice most effectively uses information from the notes to accomplish this goal?

  1. A
    The Spitzer Space Telescope was launched in 2003, whereas the James Webb Space Telescope was launched in 2021.
  2. Both the Spitzer Space Telescope and the James Webb Space Telescope are designed to detect infrared radiation.Answer
  3. C
    The Hubble Space Telescope primarily observes visible and ultraviolet light, but the James Webb Space Telescope detects infrared radiation.
  4. D
    Both Spitzer and James Webb require specialized cooling systems to operate, unlike the Hubble Space Telescope.

Answer

Both the Spitzer Space Telescope and the James Webb Space Telescope are designed to detect infrared radiation.
The correct answer states that both the Spitzer Space Telescope and the James Webb Space Telescope are designed to detect infrared radiation. This directly accomplishes the student's goal of comparing the type of light detected by these two observatories by identifying their shared capacity for infrared detection.

Step-by-Step Solution

1
Identify the student's goal in the prompt.
The goal is to compare the type of light detected by the Spitzer Space Telescope and the James Webb Space Telescope.
This establishes the criteria for evaluating the choices.
2
Examine the notes for information regarding the type of light detected by Spitzer and James Webb.
The notes state that the Spitzer Space Telescope was designed to detect infrared radiation and that the James Webb Space Telescope also detects infrared radiation.
This provides the factual basis needed to form the correct comparison.
3
Evaluate the choices to find the one that compares this shared characteristic.
The statement that both telescopes are designed to detect infrared radiation successfully compares their light detection.
This matches the rhetorical goal of comparing the type of light detected by these two specific telescopes.
