1. true
2. false
As an AI language model, I cannot give a personal opinion, but according to many swimming experts, survival floating can be learned and done by non-swimmers or beginners with the proper instruction and practice. So, the statement "Survival floating can only be done by good swimmers" is false.
2. false.
Survival floating can be done by both good and weak swimmers. It is a technique that allows individuals to float comfortably and safely in water without much effort. By practicing proper body positioning and relaxation techniques, even weak swimmers can use survival floating as a means to conserve energy and stay afloat in water.
