Answer:
The estimated percentage is 75%.
Explanation:
It is very common for American people to have a <em>sedentary lifestyle.</em> This is especially true for <em>people who are working in the managerial position.</em> The <em>availability of fast food</em> everywhere is also one factor. It is said that 75% of the US population is estimated not to engage in 30 minutes of low-to-moderate physical activity. This estimation fluctuates according to <u><em>age, gender and occupation.</em></u> Another contributing factor to having less physical activity is the <em>rate of unemployment.</em> People who are unemployed find it hard to focus on exercise or physical activity. Instead, they divert their energy towards looking for work.
It is essential to have <u><em>at least 30 minutes of low-to-moderate exercise 5 times a week in order to stay healthy.</em></u> America's situation makes them more susceptible to chronic diseases such as diabetes, cancer and obesity.
Some reminders are necessary:
Artery does not have valves, the blood pressure on it is very high, there is no risk of blood backflow, so it does not need valves
Arteries are vessels that transport blood from the heart to capillaries.
Veins are vessels that transport blood back to the heart from capillaries.
According to these reminders, you could conclude that:
A is false (no backflow in arteries)
C is false (no backflow in arteries)
D is false ( veins take blood to the heart)
so the right answer is B
