Unsupported. We only know that lab mice used in research for human health are usually kept in small cages currently. This might or might not change in the near future.

Unsupported. The reliability of current health research is reduced because mice are kept in small cages. But we don't know how better conditions would impact the research. The technician also doesn’t mention whether it's "appropriate" to use lab mice for research.

Very strongly supported. Human health research using lab mice is compromised because the mice are kept in an environment that isn’t normal for them, which reduces the reliability of the research they’re used in.

Unsupported. The technique of using lab mice is unreliable because the mice are kept in small cages. But the technician doesn’t say anything about whether researchers will develop new techniques.

Unsupported. We only know that lab mice that are used in research that is directly related to human health are usually kept in small cages. We don’t know anything about the conditions of lab mice used in other research.
