I think the answer would be A. When under stress, it can enhance a focus towards specific thing. Let’s take school for example- if you’re stressed about not having a good grade in a certain class, you might be more motivated and out focus into that’s subject. With that logic, option A would be fitting.
Most consumers are skeptical of brands and their advertising. Most marketing just wants your money and is not interested in helping you or making your life better. Here’s a reason but where’s the answer choices?
For a long time, the standard for "normal" blood pressure was 120/80. The current thinking is that a more healthy pressure is actually 110/70. 106/64 is a little lower than the norm but may be totally normal for you. If you become dehydrated it can lower your blood pressure and if your blood pressure goes too low it can cause feeling faint or passing out. If it's never been an issue and your MD doesn't have a problem I wouldn't worry.
