Correct Option
The passage explicitly states, "it was not too cold for us to take off our gloves." This indicates that the temperature inside the tent was sufficiently mild, allowing the climbers to remove their gloves. Option 1 accurately reflects this condition and action.
Incorrect Options
Option 2 is incorrect because the text clearly states it was "not too cold" for them to remove their gloves, implying they were able to do so.
Option 3 is incorrect as it misrepresents the temperature condition. The passage specifies it was "not too cold," not "very cold," when they took off their gloves.
Option 4 is incorrect because the phrase "not too cold for us to take off our gloves" implies that they did, in fact, remove their gloves, contrary to the statement that they "did not take off their gloves."
