Does a regular heart rate stay consistent? (before exercise) for example if my mine is at 80 does it stay Consistent like 80,82,84,86,88 or can it go lower or high. sorry if it doesn’t make sense

It will stay within that range as long as you don't anything; even thinking about it might change it, holding your breath, and even getting anxious about or telling a lie. So yes it will stay the same.

the correct answer is 4 (giveaways to the public)

something that is given away or gave out for free. an occasion at which things are given away to free. something that is evident or obvious; something that uncovers a mystery.

it could be be in a form of a lucky draw as well. these the company events gather more audience for their pr and it also increases their ratings as well. this is a way to attract more customers towards themselves.

your answer will be a. sorry if im wrong: )
