Final answer:
The correct answer is D) The conjecture is likely true, but more information is needed to confirm it.
Step-by-step explanation:
The correct answer is D) The conjecture is likely true, but more information is needed to confirm it.
We cannot definitively determine if the conjecture is true based on the given information. While it is stated that all the students in the Grade 8 class are at least twelve years old, we do not have information about the ages of students in other grades or classes. Therefore, it is possible that some students in other grades or classes are not at least twelve years old, causing the conjecture to be false. To confirm the conjecture, we would need more information about the ages of all the students in the school.
