True. Q's response is based on abduction reasoning, which is a type of inference that starts from an observed fact or set of facts and seeks to find the simplest and most likely explanation for those facts. In this case, Q has observed that many people complained about getting sick after eating at restaurant X and that five of their friends ended up in the hospital after eating there. Based on this evidence, Q has inferred that the food at this restaurant is not very good and that it is better not to have dinner there.
