Q: In this task, you're given a statement and three sentences as choices. Your job is to determine which sentence can be inferred from the statement. Incorrect choices change the meaning in important ways or have details that are not mentioned in the statement. Indicate your answer as 1,2, or 3 corresponding to the choice number of the selected sentence.
Statement: Caution is needed if you are not used to a hot and humid climate (a constant but not necessarily hostile factor), and often requires a little extra planning when heading out on tour, trekking, or just lazing by the pool. Choices: 1. Heat and humidity aren't a health issue even if you aren't sensitive to them. 2. Avoid too much exposure to the sun and humidity during summer times. 3. Heat and humidity should not be taken lightly if you are sensitive to it.
