When choosing vocabulary to explicitly teach, teachers should consider which of the following?
a, words that are used in multiple contexts
b. words that have definitions children can understand
c. words that can be organized in meaningful categories
d, all of these

a and b are the correct answer to what your looking fior

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
