Norder to provide a safe workout environment, an individual should check a. the condition and location of the gym equipment and temperature and ventilation in the room b. his or her strength and flexibility before planning a routine c. his or her goals and abilities before planning the workout routine d. the time, frequency, and types of exercises and equipment that he or she prefers

The answer is choice A. The condition and location of the gym equipment and temperature and ventilation in the room.

Just use common sense for questions like these.  Essentially you need to interpret the statement in a way to critically think and analyze the answer choices.  

Choice B doesn't work because the statement says "In order to provide a safe workout environment", but this answer choice says you need to check your strength and flexibility, which doesn't make much sense because you could be weak or inflexible, yet can still plan a proper routine.  Therefore, this answer is incorrect.

Choice C doesn't work because it still doesn't answer the statement.  This choice says that you should "check you goals and abilities before planning a workout routine", which doesn't answer the statement because this doesn't provide a safe workout environment.  A person doesn't have to know how strong or built they want to be to step into a gym and work out.  The statement is looking for an answer which provides a safe environment.  You can still be safe without checking goals and abilities before planning a workout.  

Choice D is the closest to the right answer, but is not quite there.  It says you should check the time, frequency, and types of exercises and equipment that he or she prefers, and which this has nothing to do with your safety in a workout environment.  It doesn't matter what time you workout; there are people that wake up at 3 AM and workout at 4 AM.  The frequency of exercises and equipment you prefer could play a role in your safety because working out vigorously could have negative impacts, but this doesn't provide a safe workout environment, therefore this answer is wrong.
