Answer to Question 1

ANY REASONABLE ANSWERS OK. EXAMPLES: RECORDING THE DATA ERRONEOUSLY TO MATCH THE DESIRED OUTCOME; TREATING SUBJECTS DIFFERENTLY BASED ON WHICH CONDITION THEY ARE RECEIVING (NOT BEING BLINDED); SUBTLY LETTING THE SUBJECTS KNOW THE DESIRED OUTCOME; EXPERIMENTER EFFECT.

Answer to Question 2

IT IS IMPRACTICAL AND MANY TIMES UNETHICAL TO SUBJECT SOMEONE TO AN EXPERIMENT WITHOUT THEM VOLUNTEERING FOR IT.

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).
