Final answer:
According to the test of utility, an anti-gravity machine theory would likely not pass the test as it lacks practical applications or evidence of feasibility.
Step-by-step explanation:
According to the test of utility, an anti-gravity machine theory would likely not pass the test. The test of utility evaluates whether a theory or idea is able to provide useful and practical applications or solutions to real-world problems. However, anti-gravity machines have not been scientifically proven or demonstrated to exist, and there are no practical applications or evidence to support their feasibility. Therefore, the theory for an anti-gravity machine would fail the test of utility.
