On Valentine’s Day, Karla streams the most romantic movie she can find on cable TV. Karla gets so engrossed in the film that she imagines she is the heroine. Lazarus’s research would suggest that Karla would experience compared to if she were not as engrossed. Group of answer choices

stronger emotions and a faster heart rate

stronger emotions and no change in heart rate

the same emotions but a faster heart rate

the same emotions and no change in heart rate

The correct answer is stronger emotions and a faster heart rate

The beat rate of a normal rested heart is 60 to 100 per minute. The atria (the two smallest chambers of the heart) contract simultaneously, and the same happens shortly thereafter with the ventricles (the two largest chambers).

This mechanism causes the characteristic “double beat” of the heart: tum-ok, tum-ok… Exercises or emotional stress can increase the heart rate to up to 200 or more pulsations. In people with a healthy heart, when the demand for effort returns to normal, the heart rate also restores quickly.

i am confused, what is the question? i can you out if you put it into more depth.
