Step 1: For inference questions, eliminate any option that needs an extra, unstated premise to be true, and keep the option that stays strictly within the scope of the given evidence.
Step 2: Option A claims failure is "necessary for every kind of success" - but the statement only covers entrepreneurs who were surveyed, not every kind of success, so this is too broad and is rejected.
Step 3: Option C claims "only people who have failed can become entrepreneurs" - this reverses the statement's logic; the statement never says failure is a requirement to become an entrepreneur, only that many who succeeded had failed earlier, so this is rejected.
Step 4: Option D brings in "formal business education", a topic never mentioned anywhere in the statement, so it is irrelevant and rejected.
Step 5: Option B stays entirely within the evidence: since many entrepreneurs failed and still went on to succeed, failure clearly did not permanently block their success.
Correct option: (2) Experiencing failure does not necessarily prevent future success.
