Final answer:
The correct paraphrase for the statement 'I don't think that he will be successful in his attempts' is option 'a) I believe he will not succeed in his attempts,' which shows a lack of confidence in the person's prospective success.
Step-by-step explanation:
The question 'I don't think that he will be successful in his attempts' implies a negative expectation regarding future success. The correct paraphrase among the given options would be 'a) I believe he will not succeed in his attempts.' This choice aligns with the sentiment of doubt about the person's success as implied in the original statement. It suggests uncertainty and lack of confidence in the outcomes of the person's efforts, thus predicting a probable failure. This is consistent with the concept of making predictions about human behavior, where we assess the likelihood of certain actions leading to success or failure. Understanding the nuances of language and prediction can be essential, especially when analyzing rhetoric or the potential outcomes of our actions in real-life scenarios.
