Read the given statements and conclusions carefully. Decide which of the given conclusions is true based the given statements. Statement: Canadian steel is harder than the steel produced in most other countries across the world. Conclusion:
I. Canadian steel manufacturers must be making a huge profit on their steel.
II. There’s something about the manufacturing process employed by Canadian steel manufacturers that makes their steel harder.

The statement makes no mention of the selling price or profitability. It is possible that there is some other aspect of Canadian steel that dissuades people from using it. Then, these manufacturers will not be making huge profits. Thus, Conclusion I is not valid. Again, we do not know whether it is something about the manufacturing process or whether it is something about the chemical composition of the raw materials used to make this steel that is responsible for this steel being harder. Thus, Conclusion It is also not valid.   Thus, neither conclusion I nor II follows. Hence, the correct answer is (D).
