this question is incomplete but I have added The Answer options to your question
a) He does not have a hypothesis.
b) He only has one group. He has not established a comparison
c) He has not measured an outcome.
d) The groups were not equal to begin with.
Answer:
b) He only has one group. He has not established a comparison
Explanation:
A randomized controlled experiment can be defined as an experiment that has two groups which it randomly assigns participants to.
These two groups are:
1.) the experimental group and
2.) The controlled group on whom the study is being performed.
Now Alberti does not have any of these groups we have listed. He performed the testing on the same people before they consumed alcohol and after they consumed alcohol. Therefore this study was not comparative in nature.

Genetic Change in Viruses. Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome.

Answer:
Heres the advice I would give to Carlos!
Explanation
The most important thing that he can do is just be there for her. Make sure that the wife knows, he's right by her side and he's with her throughout the entire way. Reinforce this by talking to her, "I love you, etc", holding her hand if possible and maintaining eye connection. This will show the wife that she is not alone in this time of pain and her worry levels will be reduced.
Also, Carlos should reassure about what is going to happen. "This is going to be over soon, etc" He should have the wife concentrate on how better everything is going to be when this is all over. When its the end, theres no going to be anymore pain, and you'll be able to feel so much better. Keep reminding her to focus on the end, once its all over, and keep her distracted from the time and what the doctors are doing. "After this, think about how much you gonna be able to do, etc" Stay positive but alert for her, so she knows your looking out.
The last thing could be, again, distracting her but with different ways. Maybe humor, making jokes to make her smile or telling her a story. In any way, give her something her mind can concentrate on instead to her focusing on the scary pain of the procedure. In any way, give a focus point to block out the pain and hang on to something more positive.
Thats all I can say, be there for her, reassure her and distract her. All of these things can reduce her worry and stress!
Hope this helped!! :)
