To determine which conclusions follow from the given statements, let's analyze the information logically. The statements provided are:
- No coin is a dollar.
- Red token is a coin.
Based on these statements, let's evaluate each conclusion:
- Conclusion I: Red token is not a dollar.
The statement "Red token is a coin" combined with "No coin is a dollar" allows us to deduce by direct extension that the "Red token is not a dollar." Thus, Conclusion I logically follows from the statements. - Conclusion II: Red token may not be a dollar.
This conclusion suggests a possibility, which does not necessarily follow from the statements since Conclusion I already asserts definitively that the red token, being a coin, definitely cannot be a dollar. Therefore, this conclusion is redundant and weak compared to the direct conclusion drawn earlier.
Based on this analysis, only Conclusion I follows logically from the given statements, which means the correct option is:
if only conclusion I follows
