Final answer:
Statement 3 is not necessarily correct as it depends on the individual and the context.
Step-by-step explanation:
Research suggests that internals ask fewer questions, are achievement oriented, and remember more information than externals. Therefore, statement 1 is correct. Additionally, internals tend to have greater motivation to achieve success and set high standards for themselves, which supports statement 2 being correct. However, it is not accurate to say that internals remember more information than externals as this can vary depending on the individual and the context. Therefore, statement 3 is not necessarily correct. The correct answer is B) Only statements 1 and 2 are correct.
