Answer:

No, because this is an observational study.

Step-by-step explanation:

The researchers found that the rate of leukemia for children near​ high-tension wires was higher than the rate for those not near​ high-tension wires.

So, the answer is No, the researchers cannot conclude that proximity with​ high-tension wires causes leukemia in​ children as this is only an observational study.

Observational study is that study where the researcher observes the effect of a risk factor, diagnostic test or treatment without trying to control who is or is not exposed to it.

<h3>Bob walked faster than Ion.</h3>
