question 4 (1 point)

• passage: the theory of plate tectonics provides an explanation for the movement of earth’s lithospheric plates. this movement is responsible for many geological events, such as earthquakes and the formation of mountains. the theory suggests that the plates float on the semi-fluid asthenosphere and interact at plate boundaries.

what is the main idea of the passage?
○ a the lithospheric plates are responsible for the earth’s rotation.
○ b plate tectonics explains the movement of earth’s plates and geological events.
○ c the asthenosphere is solid and immobile.
○ d plate boundaries are the only areas affected by tectonic activity

Explanation:

First Question (When is reasoning most effective in CER writing?)

In CER (Claim - Evidence - Reasoning) writing, reasoning is meant to connect the evidence to the claim. Option a is incorrect because reasoning should not change the original claim. Option b is wrong as reasoning should focus on the existing claim and evidence, not introduce new topics. Option d is incorrect because CER relies on logical explanation, not emotional appeal. Option c is correct as reasoning's main role is to explain why the evidence supports the claim.

The passage states that the theory of plate tectonics explains the movement of Earth’s lithospheric plates and that this movement causes geological events like earthquakes and mountain formation. Option a is wrong as the passage doesn't say plates are responsible for Earth's rotation. Option c is incorrect because the passage says the asthenosphere is semi - fluid, not solid and immobile. Option d is wrong as the passage doesn't state that plate boundaries are the only areas affected. Option b accurately summarizes the main idea of the passage.

Answer:

c. When it explains why the evidence supports the claim
