which phrase describes a claim that is “debatable”?

b. An idea that is open to discussion.
c. An idea about a topic that is not grounded and evidence.
d. An idea to be shared in front of a group of people.

b. An idea that is open to discussion.

b. An idea that is open to discussion.

The phrase that describes a claim that is "debatable" is option b: "An idea that is open to discussion."

To understand why this is the correct answer, let's break down the meaning of the word "debatable." When something is "debatable," it means that there are different opinions or perspectives on the matter, and it is open to discussion and argumentation.

Option a, "An idea that can be supported by facts," is not the correct answer because a claim that can be supported by facts is not necessarily debatable. If there is indisputable evidence supporting the claim, then it is considered factual and not open to debate.

Option c, "An idea about a topic that is not grounded in evidence," does not accurately describe a debatable claim either. Claims that lack grounding in evidence are typically seen as weak or invalid, and there would be little room for debate on such claims.

Option d, "An idea to be shared in front of a group of people," does not pertain to the concept of debatability. Sharing an idea in front of a group of people does not automatically make it debatable. The debatability of a claim lies in the nature of the idea itself, not in the act of sharing it with others.

Therefore, the best description of a claim that is "debatable" is an idea that is open to discussion, which is option b.
