Dr. kovacs is conducting a study of how the brain responds to reading. he records subjects’ brain activity using electroencephalography (eeg) while they read sentences. he is looking for the n400 signal, a negative eeg spike that occurs 400 milliseconds after someone processes something semantically surprising. there are two conditions in the study. the two figures below show average eeg activity for the subjects in the two conditions (condition a on the left; condition b on the right). the x-axis indicates time in milliseconds; time 0 indicates when the subjects first read the last word in each sentence. which of the following pairs of conditions would produce results such as the ones dr. kovacs found? a. condition a included sentences such as "strawberries are sweet," and condition b included sentences such as "strawberries is sweet."b. condition a included sentences such as "strawberries is sweet," and condition b included sentences such as "strawberries are sweet."c. condition a included sentences such as "strawberries are nervous," and condition b included sentences such as "strawberries are sweet."d. condition a included sentences such as "strawberries are nervous," and condition b included sentences such as "strawberries are furious."e. condition a included sentences such as "strawberries are sweet," and condition b included sentences such as "strawberries are nervous."
