The most reasonable answer i think would be option b: building pedestrian-friendly walkways.
Why? because if they would have to purchase bikes for each household, that would be too expensive.
I think option 3 does not even go in these categories.
And option 4: think not all senior citizens go to the gym. They usually might just walk around the neighborhood once or twice, and go to bed, because their legs hurt.
That is why i think option 2 fits best here.
Hope i helped!

Answer:
To find your heart rate, there are a lot of ways to do it but <u>neck and wrist </u>are the top two i'd say.
Neck: Take two fingers and place them in the more hollow part of your neck by your "adam's apple" (or larynx) in the middle (place them on any side but it might be easier on the <u>right</u>).
Wrist: To find your wrist pulse, you take two fingers again and put them on the same side of your wrist as your thumb, by the bone in the middle. If you don't know what I'm talking about there is a bone right in the middle of you arm (starts at the wrist pretty much) and to the same side of your wrist as your thumb, if you place your two fingers there you will find a pulse!
{The equation to find maximum heart rate is to take your age and subtract it from 220.}
<u>BUT,</u> to find the regular heart beat at that second all you have to do is count how many beats you have in 15 seconds and multiply that number of beats by 4 to know your beats per minute.

I hope this helped you and makes sense!
