Question

which of the following is an example of a claim? earths magnetic field is pointless and needs to be eradicated. what is the purpose of the earths magnetic field? scientific research has proven that the earth is a giant magnet.

Explanation:

A claim is a statement that presents an assertion or opinion. The first option "Earth's magnetic field is pointless and needs to be eradicated" is a claim as it presents a subjective opinion. The second option is a question, not a claim. The third option is a factual statement based on scientific research (if we assume it's a well - established fact), which is more of a factual assertion rather than a claim in the sense of a debatable opinion.

Answer:

"Earth's magnetic field is pointless and needs to be eradicated."
