View the photo below, read the passage, and answer the question.



The arcs in the photo are background galaxies that were distorted and magnified by a giant cluster of dark matter. As the light leaves its source, the gravity of the cluster of dark matter bends that light, creating the swoops in the image above.

This passage best supports which conclusion about dark matter?

a. Dark matter does not give off light, but scientists can see the reflection in stars around it
b. Dark matter is created from clouds of dust and gas scattered throughout the universe
c. Dark matter has a significant impact on the stellar life cycle
d. Dark matter does not give off light, so it can only be detected by observing the effects of gravity on visible objects nearby

This chart lists four examples of two objects that are in contact.

A 3-column table with 4 rows. The first column has entries Example 1, Example 2, Example 3, Example 4. The second column labeled Object 1 has entries fire, a metal at 80 degrees Celsius, the cool ocean, a tool with a lot of thermal energy. The third column labeled Object 2 has entries air, a metal at 12 degrees Celsius, the warm air, a material with little thermal energy.

Which statement accurately describes the flow of heat in each example?

Heat will flow from Object 1 to Object 2 in examples 2 and 4, and heat will flow from Object 2 to Object 1 in examples 1 and 3.
Heat will flow from Object 1 to Object 2 in examples 1 and 3, and heat will flow from Object 2 to Object 1 in examples 2 and 4.
Heat will flow from Object 1 to Object 2 in Example 3, and heat will flow from Object 2 to Object 1 in examples 1, 2, and 4.
Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3.
