Digital SAT Reading and Writing Practice Question #847

While researching exoplanetary atmospheres, a student took the following notes: • Exoplanet WASP-121b is an ultra-hot Jupiter orbiting an F-type star every 1.27 days. • Spectroscopic observations by the James Webb Space Telescope revealed gaseous iron and titanium in WASP-121b’s upper atmosphere. • The day-side temperature exceeds 2,500 Kelvin, vaporizing refractory heavy metals. • On the planet’s night-side, temperatures drop to 1,500 Kelvin, allowing iron to condense and precipitate as liquid metal rain. • The student wants to highlight the dramatic temperature difference between the planet's two hemispheres and its physical consequence. Which choice most effectively uses the relevant information from the notes to accomplish this goal?
