Answer to Question 1

False

Answer to Question 2

All the stars in a cluster are understood to have formed at about the same time from the same cloud of gas, so they are all about the same age and have the same chemical composition. The differences you see among stars in a cluster presumably arise only from differences in mass, and that is what makes stellar evolution visible.

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
