Sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect. Recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth.

Which of the following, if true, most seriously weakens the argument?
A Experimental subjects who used the zinc gel not only had colds of shorter duration but also had less severe symptoms than did those who used a gel that did not contain zinc.
B The mechanism by which zinc affects the viruses that cause the common cold has not been conclusively established.
C To make them palatable, zinc lozenges generally contain other ingredients, such as citric acid, that can interfere with the chemical activity of zinc.
D No zinc-based cold remedy can have any effect unless it is taken or applied within 48 hours of the initial onset of cold symptoms.
E Drug-company researchers experimenting with a nasal spray based on zinc have found that it has much the same effect on colds as the gel does.

There is a huge database of questions from various sources which are discussed extensively in the forums and there is a high probability of finding answer to your question in the existing topics. After you do the necessary search using the "search" option, if you find that the question already exists and that you have additional queries which is not discussed there already, then put your question in the existing topic. Kindly do not NOT start another thread on the same question.

Also the question need to be entered completely as found from the original source. Here first word of the question is missing.

This is a duplicate post and hence locked.
