Take the following as truth: 3 It should be noted that the toxicity (LC50) of a sample observed in a range-finding test may be significantly different from the toxicity observed in the follow-up chronic definitive test  (1) the definitive test is longer; and (2) the test may be performed with a sample collected at a different time, and possibly differing significantly in the level of toxicity.
Then the following statement: "The toxicity of a sample in the range-finding test might be very different from the toxicity in the follow-up test." is true, false, or inconclusive?
Answer: True
