You can easily remember your birth date; perhaps you can also remember what you did on your last birthday. the difference between these two pieces of knowledge can best be characterized as a difference between:

Semantic vs. Episodic Memory

Explanation:

Semantic memory is an organized record of knowledge, meanings, facts and concepts about the world. Semantic is about simple knowledge, which includes types of dress, food, social etiquette, etc.

Episodic memory is about our memory of a person's experiences of specific events or incidents in time in a serial form. This memory is autobiographical in nature and includes places, times, and emotions.

In this case, remembering birth day is semantic memory while what actually happened on the last birth day is episodic memory.

the civil rights act was passed on april 9, 1866 by a republican dominated congress. it was passed over president johnson's veto, in an effort to push back against discrimination of african americans.

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 !
