Research shows that minutes a week of moderate intensity aerobic activity, such as brisk walking, consistently reduces the risk of many chronic diseases and other adverse health conditions? a.90 b. 120 c. 180 d. 150 i need to get this right only answer if you know this for sure

I know the Mayo Clinic says 150 minutes, so I think D would be your answer.

I’m going to guess these are the choices: a) recreational skiing developed in the mid-19th century b) it was originally invented as a way of getting from place to place in snowy regions c) downhill skiing is currently the only common form of the sport d) it mostly evolved from snowshoeing- if that’s the cases then the answer would be c) downhill skiing is currently the only common form of the sport

Iwould say a is correct
