Penfield opened the skulls of conscious epileptic patients under local anesthesia, and induced a mild electric current into their brains in an attempt to pinpoint the source of seizure activity and then remove that piece of issue. What he found was even more remarkable that what he initially set out to do. By stimulating different points on the lower part of the brain(the temporal lobes), he elicited distinct and vivid memories in his patients.
All the following are mentioned in paragraph 1 as part of the surgical procedure Penfield perfomed on his patient except:
A)Penfield stimulated different points in his patients' temporal lobes B) Penfield's epileptic patients were not totally anesthetized during the surgery C) the patients' brains were given small electric shocks during surgery D)Penfield removed the pieces of tissue responsible for inducing seizures in his patients E)The patients' skulls were wide open throughout the surgery
I can't understand Why the correct answer is D instead of E.. where is there written wide open in the text?

First I will tell you whyDis right: Penfield opened the skulls of conscious epileptic patients under local anesthesia, and induced a mild electric current into their brains in an attempt to pinpoint the source of seizure activity and then remove that piece of tissue. we only know that penfield was planning to remove the tissue finally.....but in the lines that follow its only told what he observed.....we do not know whether he finally removed the tissues or not... Now E:Penfield opened the skulls of conscious epileptic patients under local anesthesia.....i guess you have a doubt with the word 'wide'? well you can pretty sure if your skull is under open surgery....it will be pretty wide open...
