Explaining Relationships in Texts

Question 1

Read the passage below. "Water from lakes, rivers, and oceans is heated by the sun and changes into water vapor in a process called evaporation. The water vapor rises into the sky, where it cools and changes back into tiny droplets, forming clouds in a process called condensation. When the droplets become heavy enough, they fall to the ground as precipitation, such as rain or snow. The precipitation collects in bodies of water, and the cycle begins again." According to the passage, which of the following best describes the relationship between evaporation and precipitation?

Accepted Answer

Evaporation creates water vapor that eventually becomes precipitation after rising, cooling, and condensing into clouds.

Answer

Evaporation and precipitation are unrelated processes that occur independently.

Answer

Precipitation causes evaporation by returning water to the atmosphere.

Answer

Evaporation directly produces precipitation without any intermediate steps.

Question 2

During the summer of 2022, 12‑year‑old Jamal joined his school's eco‑club. He suggested that the club organize a “Bike‑to‑School” day, where students would ride bicycles instead of taking the bus. Jamal created flyers, spoke with the principal, and set a schedule for the first week of October. After the event, many students told their parents about the idea, and the local newspaper wrote a story about the reduced traffic near the school. Over the next two months, the school cafeteria switched from disposable plastic trays to reusable ones, saying the change was inspired by the lower amount of litter they observed during the bike days. How did Jamal’s actions influence the cafeteria’s decision to use reusable trays?

Accepted Answer

His bike‑to‑school event reduced litter, which led the cafeteria to adopt reusable trays.

Answer

He personally replaced the plastic trays with reusable ones.

Answer

The principal decided to change the trays after reading Jamal’s flyers.

Answer

The newspaper’s story directly ordered the cafeteria to switch trays.

Question 3

Read the passage below: "When a steel nail is left in a salty lake, it slowly turns reddish‑brown. First, a thin layer of water molecules sticks to the nail’s surface. Next, oxygen from the air mixes with that water layer and forms a tiny film of iron oxide. Finally, that iron oxide reacts with more oxygen and water, spreading the rust over the nail." Which statement best explains how the three steps depend on each other?

Accepted Answer

The water layer must attach to the nail first so that oxygen can later combine with it; without that first step, the later rust formation cannot happen.

Answer

All three steps happen at the same time, so the order doesn’t matter; the nail rusts whenever water and oxygen are present.

Answer

The last step creates the water layer that then draws in oxygen, so the final step actually starts the whole process.

Answer

Only oxygen is needed for rust; the water layer is unnecessary, so the first two steps can be skipped.
