Question

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

select the best answer for each of the following reading questions:

question 5 (1 point)
which statement represents the weakest claim that needs revision?
○ a students should wear uniforms because i think so.
○ b things are happening in the world
○ c social media impacts teen mental health negatively
○ d renewable energy reduces carbon emissions.

Explanation:

First Question (Main Idea of the Passage)

• Option a: The passage says the theory of plate tectonics explains Earth’s lithospheric plate movement and that this movement causes geological events (earthquakes, mountain formation). This matches the main idea.
• Option b: The passage doesn't say plate boundaries are the only areas affected; it just mentions interaction at boundaries. Eliminate.
• Option c: The passage is about plate movement, not Earth’s rotation. Eliminate.
• Option d: The passage states the asthenosphere is semi - fluid, not solid and immobile. Eliminate.

• Option a: “Students should wear uniforms because I think so” is a weak claim as it's based on personal opinion with no evidence or reasoning.
• Option b: “Things are happening in the world” is a very general and vague statement but not a claim that needs revision in the same way as a poorly supported opinion - based claim.
• Option c: “Social media impacts teen mental health negatively” can be supported with research/evidence.
• Option d: “Renewable energy reduces carbon emissions” is a claim supported by scientific evidence.

Answer:

a. Plate tectonics explains the movement of Earth’s plates and geological events
