Teacher:You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Teacher: Now, understand the problem? Solve this instance: What you are probably using is called pharmaceutical sulfur. It is used as a scabicide, parasiticidal, and antiseptic. There are three forms. Precipitated sulfur, sublimed sulfur, washed sulfur. Sublimed and washed sulfur are in the form of a fine yellow crystalline powder, with only a faint odor and taste. Precipitated sulfur is a very fine pale yellow amorphous or microcryst powder, which is odorless and tasteless. I am still looking for toxicity data and I will update my answer if I find anything. I wouldn't worry about using it, the cure is probably better than the illness. But always talk to a doctor before starting any kind of treatments.
Student:
I have to put sulfur in my hair and have been mixing it with aloe vera gel.There is an odor.Is this toxic?
