An important study at a major university has determined that a chemical found in the typical American diet is extremely dangerous. Dihydrogen monoxide, which is added to many processed foods, has been linked to a number of deaths among people, especially swimmers. Although it is normally a liquid, in its gaseous state it can cause severe burns. Dihydrogen monoxide can even corrode metal. Many drivers involved in automobile accidents had drunk dihydrogen monoxide shortly before driving. Why is this substance added to our food?

What are four bias questions that determine whether the information about dihydrogen monoxide is biased?

When one refers to a biased question, one is discussing a question that would focus on a specific topic that would enable one to obtain the answer one desires.

The topic that you provided skips around addressing several issues related to dihydrogen monoxide. To establish questions that are biased, let us look at the topics and separate them.

1) One subject area addresses a link between dihydrogen monoxide as a cause of deaths.  

A biased question could read as follows:

Why does dihydrogen monoxide cause death among people who eat food that contains the substance?

The question demonstrates bias by stating that dihydrogen monoxide causes death.

2)  The first sentence also implies that swimmers are more likely to die from dihydrogen monoxide. 

Do more swimmers die from dihydrogen monoxide because they swallow it in pool water?

One can not prove this question when converting it to a hypothesis because studying swimmers alone is subject bias, and swimmers may swim other places than pools.

3)  Another statement expresses that dihydrogen monoxide causes many automobile related deaths. Changing this statement into a question provides bias.

Why are many automobile accidents caused by people who drink dihydrogen monoxide before they drive?

4) A fourth statement indicates that in a gaseous state dihydrogen monoxide causes severe burns.

Why does dihydrogen monoxide only cause severe burns when it is in a gaseous state?

The bias exists because the question indicates that the chemical only causes burns when it is in a gaseous state and does not account for the possibility that the chemical may cause burns in a liquid state.
