The anthropologist claims that the results of the test were invalid, with the implication being that she didn't commit fraud. The reason she gives for the test results being invalid is that the medicinal powder was tested in an acidic solution.

The anthropologist assumes that exposure to an acidic solution somehow rendered the test results invalid, perhaps because acid reacts with toxin T to turn it into something else.

The external evidence the anthropologist had going into the experiment doesn't tell us anything about the claim that testing the powder in an acidic solution invalidated the results.

We don't know if the powder used in the test was stored for a long time, and even if it was, just because a toxin is less active doesn't mean it isn't present. This answer choice doesn't connect to the anthropologist's argument that testing the powder in an acidic solution somehow means the results, which said toxin T was not present, were invalid.

This answer choice establishes that using an acidic solution for this test would totally compromise the search for toxin T. Thus, the test results truly were invalid.

The information about what could hypothetically have happened after the first test neither strengthens nor weakens the claim that the results of the first test were invalid because of the acidic solution.

This answer choice doesn't strengthen the anthropologist's claim about an acidic solution somehow rendering the results of the test invalid.
