Answer:
They waited before crossing a busy street
Explanation:
Assume the graph looks like the one below.
It shows that, from Point B to C, the distance they were from home did not change. They had stopped.
A possible interpretation is that they waited before crossing a busy street.
If they had begun accelerating, BC would have been steeper than AB.
If they had slowed their walk, BC would still point up. However, its slope would be less than that of AB.
If they had returned home, BC would point down and to the right.
Answer:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
