Question

read the passage. then answer the question.
tornadoes occur during storms when warm air near the ground rises and meets cooler air above. the warm air moving up and cold air moving down at different speeds create powerful winds that spin around. sometimes these spinning storms form funnel clouds that reach to the ground. the resulting funnel cloud is a tornado.
which signal word lets you know that this passage has a cause and effect structure?
a occur
b moving
c different
d resulting

Explanation:

In a cause - and - effect structure, words that show a relationship where one thing leads to another are key. "Resulting" indicates that something (the funnel cloud) is the outcome (effect) of a previous situation (the cause of the spinning storms). "Occur" just states an event, "moving" describes an action, and "different" is a descriptive adjective. None of these other words signal a cause - and - effect relationship like "resulting" does.

Answer:

D. resulting
