Question

scientists have been experimenting with gene therapy, which often involves the use of bacteria or viruses to deliver new or modified genes to cells. these scientists believe gene therapy can be used to treat inherited diseases, but it is not yet in wide use even though many people have studied it. which statement best describes gene therapy?
the idea has not yet achieved scientific consensus.
the idea has gained scientific consensus against its use.
the idea takes too long to test to develop scientific consensus.
the idea is supported by most scientists, but a vocal minority disagrees.

Explanation:

Gene therapy is still an area of active research. While scientists are experimenting with it and see its potential for treating inherited diseases, it has not yet reached a point where there's a scientific consensus (it's not fully established as a standard treatment with widespread agreement on its safety and efficacy across the scientific community). The other options: gaining consensus against use is incorrect as research is ongoing to explore its use; it's not too new to test (research is happening); and while there may be some debate, the key is it hasn't achieved the level of scientific consensus yet.

Answer:

A. The idea has not yet achieved scientific consensus.
