Read the two excerpts from Chapter Four of Windows to the Universe: Revolutions in Astronomy.Light travels at a speed of approximately 186,282 miles per second. That's pretty fast, but the universe is a huge place! For example, light from the Sun takes about 8 minutes to reach Earth, so we see the Sun as it was 8 minutes ago. For more distant objects, this delay can be millions or billions of years.NASA scientists set specific goals for JWST, which helped shape its design and capabilities. The goals of JWST are:Search for the first galaxies and sources of light formed right after the Big Bang.How do these two excerpts together explain why JWST was designed to study the early universe?

A
They explain that JWST was built to detect the fastest-moving objects in the universe.
B
They show that because light takes time to travel, JWST can capture images of galaxies as they appeared billions of years ago.
C
They suggest that JWST can travel back in time to directly observe and capture images of the Big Bang as it happened.
D
They indicate that because sunlight takes 8 minutes to reach Earth, JWST's primary goal is to measure the exact speed of light in space.

Read the two excerpts from Chapter Four of Windows to the Universe: Revolutions in Astronomy.One of the most significant challenges in JWST's design was ensuring the sunshield could unfold correctly after launch. It had to be folded precisely to fit into the spacecraft and then unfurl perfectly once in space—like a massive piece of origami. The success of this deployment was critical to the mission. When flight control confirmed it had unfolded correctly, the entire control room erupted in cheers!The JWST orbits at a location called Lagrange Point 2 (L2), more than one million miles from Earth. Lagrange points are areas where the gravitational forces of the Sun and Earth balance out, allowing an object like a telescope to stay in a stable orbit. Stationing JWST at L2 keeps the sunshield properly positioned to protect its instruments and ensures that the telescope always aligns with the Earth, making communication easier.What conclusion can best be drawn about JWST’s design and function?

A
JWST's most important feature is its ability to change locations to avoid too much sunlight.
B
JWST was launched into an unstable orbit, making communication with Earth more difficult.
C
JWST's success depended on both careful engineering and precise placement in space.
D
JWST's sunshield was designed mainly to help the telescope generate power from the Sun.

Look at the timeline excerpt from Chapter Four of Windows to the Universe: Revolutions in Astronomy.1989: The first conference to discuss a space-based infrared telescope is held.1996: A committee of 18 members is selected to review designs.2002: Teams are selected to build components, and the telescope is named after former NASA administrator James Webb.(Several more events listed with just the year)December 25, 2021: JWST is launched.January 24, 2022: JWST reaches Lagrange Point 2.July 12, 2022: The first images from JWST are released to the public.What is the effect of including specific months and days for the last three events in the timeline, while the earlier events only include years?

A
It highlights delays in the telescope’s construction and testing.
B
It provides exact dates to compare JWST with other missions.
C
It emphasizes the precise timing of JWST’s most critical milestones.
D
It shows that the telescope’s early development was less important than its launch.
13

Look at the timeline excerpt from Chapter Four of Windows to the Universe: Revolutions in Astronomy.2013-2016: Extensive testing is conducted on all components.Why did the author most likely include a range of years in this entry?

A
to show that testing was a lengthy and ongoing process
B
to imply there were many technical failures during testing
C

Question illustration
A
The sunshield is crucial for keeping the telescope's cameras clean from dust in space.
B
The sunshield's ability to unfold correctly was critical because its multiple layers protect the telescope's instruments from heat.
C
The sunshield was designed mainly to help JWST collect solar energy, which would then be used to power its instruments.
D
The sunshield is difficult to deploy because it is made of a solid metal sheet that completely blocks all heat.
