Final answer:
Gravity is a fundamental force that attracts objects, with evidence that objects fall towards the Earth and the force is stronger with larger masses. Gravity is solely responsible for objects falling to Earth, with evidence that objects consistently fall towards the Earth's center and the force is proportional to mass.
Step-by-step explanation:
A. Claim: Gravity is a fundamental force that attracts objects. Evidence: Objects fall towards the Earth, and the force is stronger with larger masses. Reasoning: This consistent behavior supports the idea that gravity is a universal force acting on all objects.
D. Claim: Gravity is solely responsible for objects falling to Earth. Evidence: Objects consistently fall towards the Earth's center, and the force is proportional to mass. Reasoning: These patterns support the conclusion that gravity is the primary force at play.
Based on observations, the Claim-Evidence-Reasoning (CER) regarding gravity would include both A and D. A provides evidence that objects fall towards the Earth and the force is stronger with larger masses, supporting the claim that gravity is a fundamental force that attracts objects. D supports the claim that gravity is solely responsible for objects falling to Earth, with evidence that objects consistently fall towards the Earth's center and the force is proportional to mass. These observations and patterns strongly reinforce the concept of gravity as a universal force acting on all objects, making it the primary force at play.
