Fluid accumulation is the primary symptom of right-sided heart failure. Your feet, ankles, and legs will swell (edema) as a result of this buildup.
There is either low blood pressure or high blood pressure (130/80 mm Hg or above). Low blood pressure may indicate advanced heart failure. There is a third heart sound, which denotes irregular blood flow via the heart. There may or may not be heart murmurs. Consequently, the right chamber can no longer pump when you develop right-side heart failure. It follows that when your heart cannot pump enough blood, blood backs up into the veins. Your abdomen, ankles, and legs may likely enlarge if this occurs.

Answer:
<u>The frequency of “c” would increase.</u>
Explanation:
Remember, in the scenario, we are told the carrier survives better in an environment with severe diarrhea.
<u>Hence, it is thus logical to expect the frequency of </u><u><em>"c" </em></u><u>to increase in an environment where there was an epidemic of cholera.</u>
Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
