SAT Reading and Writing · Rhetorical Synthesis Practice Question

While researching a topic, a student has taken the following notes: <ul> <li>The Hubble Space Telescope, launched in 1990, orbits Earth at about 547 km altitude.</li> <li>The James Webb Space Telescope, launched in 2021, orbits the Sun at the L2 Lagrange point, 1.5 million km from Earth.</li> <li>Hubble observes primarily in visible and ultraviolet wavelengths.</li> <li>Webb observes primarily in infrared wavelengths.</li> <li>Webb's larger mirror (6.5 m) gathers more light than Hubble's (2.4 m).</li> </ul> The student wants to contrast the two telescopes' observation capabilities. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Which choice most effectively makes the student's point?

A
$While Hubble observes primarily in visible and ultraviolet wavelengths, Webb observes primarily in infrared.$

B
$Both Hubble and Webb are space telescopes that have made important discoveries.$
C
$Webb's mirror is 6.5 m, and it orbits at the L2 Lagrange point.$
D
$Hubble launched in 1990 and Webb launched in 2021.$

Explanation

The goal is to contrast observation capabilities. Choice C directly contrasts the wavelengths each telescope sees. A contrasts launch dates, B states a similarity, and D describes only Webb.
