Which of the following statement is incorrect.

Question

BlackTom AI · Accepted Answer

The question asks which of the following statements is incorrect. Below is a breakdown of each option to evaluate its truth value.

Option a: 'An experiment can be carried out in a controlled manner' — This is generally true. A key hallmark of experimental methodology is the control of variables to isolate effects, so conducting an experiment in a controlled manner reflects core scientific practice. The reasoning here relies on the standard experimental design principle of controlling extraneous variables to test a hypothesis.

Option b: 'The results of an experiment can be duplicated' — This is also true. Replicability or repeatability is a fundamental criterion of scientific validity; if results cannot be duplicated by others under the same conditions, the reliability of the finding is questioned. Thus, duplication of results is expected in sound experimental work.

Option c: 'None' — Interpreting this as 'None of the statements are incorrect' would be true only if all statements were correct. Since we have identified at least one statement that is not accurate (see option d below), this option becomes incorrect because there exists at least one incorrect statement among the set.

Option d: 'An experiment can be done by all researchers' — This is typically false. Not all researchers have equal access to resources, equipment, time, or training required to perform experiments. Practical constraints and varying expertise mean that not every researcher can conduct any given experiment. Therefore, this statement is incorrect.

Summary of the logical gaps:
- A is correct because controlled experimentation is a standard practice.
- B is correct because duplicability is a core expectation of experimental results.
- C is incorrect because the presence of an incorrect statement (D) means 'None' is not true.
- D is incorrect because it overstates universal accessibility of performing experiments across all researchers.

Note: The final determination depends on how the question interprets 'incorrect' and on which statements are being evaluated as correct in the given context. Here, the analysis shows that options C and D are not consistent with standard scientific practice, while A and B are consistent.
