Question
The acetone test has given us new evidence.
The suspects did not use gold paint, so Hypothesis 1 is not correct.
Hypothesis 1: The suspects painted the silver-looking coins with gold paint. The gold paint would add matter to the silver-looking coins. The zinc metal could help the gold paint look real.
Hypothesis 2: The suspects heated the silver-looking coins. This mixes the zinc and copper metals. Mixing does not add matter. This mixture makes the coins look gold.
Explain how the new evidence showed that Hypothesis 1 is not correct.

From the given statement, we can infer that the evidence was obtained through the acetone test. The acetone test is used to determine whether a surface has been painted with a lacquer or other coating by analyzing whether the coating dissolves in acetone or not. Therefore, the acetone test was probably performed on the suspected coins to find out if they had a coating of gold paint on them.
If Hypothesis 1 were true, then the acetone test would have shown that the suspected coins had a coating of gold paint, which would have dissolved in the acetone. However, since the statement clearly states that the suspects did not use gold paint, it can be concluded that the acetone test did not show the presence of gold paint on the coins. Therefore, this new evidence contradicts Hypothesis 1, and it can be concluded that Hypothesis 1 is not correct.
