Question

which most likely is a causal relationship? an experimenter showed different causes for two patients lung cancer. one experiment showed that all cancers can be cured by a new drug. experimenters show a link between adult - onset diabetes and obesity. experimenters show statistical data on diabetes drugs.

Explanation:

A causal relationship implies that one variable causes another. Showing different causes for two patients' lung - cancer indicates individual factors leading to the disease, which is a form of causal analysis. Statistical data only shows associations, a link is not necessarily causal, and a claim that all cancers can be cured by a new drug is more of a statement about treatment efficacy rather than a clear - cut causal relationship.

Answer:

An experimenter showed different causes for two patients' lung cancer.
