To identify sentence completeness errors, we need to analyze each of the given sentences individually.

1. "The meteorologist reported a hurricane was approaching."
This sentence is grammatically incorrect because it lacks a verb connecting the subject ("a hurricane") to the rest of the sentence. To correct it, we can add the verb "was" before "approaching":
"The meteorologist reported that a hurricane was approaching."

2. "In the honors program, course offerings are multidisciplinary; course structure is flexible."
This sentence is grammatically correct and complete. It consists of two independent clauses separated by a semicolon. There is no error in sentence completeness here.

3. "Team members learn both to work and to take risks together."
This sentence is grammatically correct and complete. It includes a subject ("Team members") and a verb ("learn"), and the phrase "both to work and to take risks together" completes the meaning of the sentence. No error in sentence completeness is present here.

4. "John F. Kennedy’s consumer bill of rights focused on the right to be safe, to be informed, to choose, and to be heard."
This sentence is grammatically correct and complete. It contains a subject ("John F. Kennedy’s consumer bill of rights") and a verb ("focused"), and the phrase "on the right to be safe, to be informed, to choose, and to be heard" completes the meaning of the sentence. There is no error in sentence completeness here.

In conclusion, the only sentence that contains an error in sentence completeness is the first one. The corrected version would be: "The meteorologist reported that a hurricane was approaching."
