Drake's sum of 234 and 75 being 984 indicates that he made a significant error in his calculation. Each of the provided options can be analyzed to identify the source of the mistake:
1. **Drake did not align the digits by their place value when he set up the problem.** - If he misaligned the digits, he would not correctly add them, possibly resulting in a large incorrect sum, which aligns with the erroneous total of 984.
2. **Drake multiplied the numbers instead of adding them.** - Multiplying 234 by 75 would not lead to a sum like 984; it would yield a much larger product, which indicates this is not the case.
3. **Drake added 234 and 57 by mistake.** - Adding those numbers gives 291, which is also not close to 984.
4. **Drake did not regroup correctly after adding the ones digits.** - This could potentially lead to an incorrect result, but it would not typically lead to a sum as high as 984 from those smaller numbers.
Given the context and the nature of the problem, the most plausible explanation for reaching 984 is that **Drake did not align the digits by their place value when he set up the problem.** So the answer is:
**Drake did not align the digits by their place value when he set up the problem.**
