Question

read a text about déjà vu.
déjà vu is the strange feeling that an event that is currently happening has somehow already happened before. researchers estimate that two - thirds of people have felt déjà vu before. yet the causes of déjà vu remain a mystery. this, at least in part, is because the phenomenon is extraordinarily difficult to study in a laboratory. by its very nature, déjà vu is spontaneous and unpredictable. we cant make it happen, nor can we know when it will happen. its also very infrequent. it wouldnt be practical to bring people into a lab and simply wait for déjà vu to occur; chances are, it wont.
select the two details that are included in the text.

Explanation:

1. For the first detail: The text states déjà vu is hard to study in a lab, which is a controlled environment, and this limits research. This matches the text.
2. For the second detail: Temporal lobe epilepsy is not mentioned anywhere in the provided text, so this is not included.
3. For the third detail: The text says déjà vu is "spontaneous and unpredictable", which means it occurs randomly and without warning. This matches the text.
