Question

1. which of the following is a counterexample for the given conjecture?

conjecture: all students have school pride.
jose goes to school every day.
jessica studies and is attentive in class.
john does not wear his school colors and does not attend any school events.
joanna always wears her school colors and attend all school events she possibly can.

Explanation:

A counterexample to the conjecture "All students have school pride" must show a student lacking school pride. John not wearing school colors and not attending school events indicates a lack of school pride, contradicting the conjecture. Jose going to school, Jessica being attentive, and Joanna wearing school colors/attending events support or don't contradict the conjecture.

Answer:

B. John does not wear his school colors and does not attend any school events.
