We start by restating what the problem asks: compute overhead rates using activity-based costing (ABC) and round to the nearest dollar (0 decimal places). The two blanks correspond to two separate overhead cost pools and their respective activity drivers: Machining per machine hour, and Machine Setup per setup hour.

In ABC, each overhead cost pool is assigned to products based on a chosen activity measure (driver) that correlates with the consumption of the overhead pool. The typical steps are: (1) identify cost pools (e.g., machining overhead, setup overhead), (2) determine an appropriate activity driver for each pool (e.g., hours of machine time for machining, number of setups for setup overhead), (3) compute the rate for each pool by dividing the total overhead in that pool by the total activity of its driver, and (4) apply these rates to products based on their usage of the drivers. The problem provides final numeric results for the two rates, so we evaluate them in light of this ABC framework.

Option analysis for the Machining rate per machine hour being 80:
- If the total machining overhead allocated to all products is, for example, $X and the total machine hours across all products are H, then the ABC machining rate would be X / H. The given value of 80 implies that X / H = 80, meaning that for each machine hour used, $80 of machining overhead is allocated. This would be consistent with a scenario where machining overhead is relatively high per hour, possibly due to expensive tooling, depreciation, or maintenance that scales with machine usage.
- A possible pitfall in interpreting this value is assuming this rate applies to all products equally without considering driver accuracy. In ABC, accuracy hinges on using the correct driver (machine hours) and ensuring the cost pool is indeed driven by machine time; otherwise, the rate could misstate product costs.

Option analysis for the Machine Setup rate per setup hour being 210:
- This rate is computed as the total machine setup overhead allocated divided by the total number of setups (rate = Setup Overhead / Setups). A rate of 210 per setup hour suggests there are costly setup activities per setup, such as complex retooling, calibration, or downtimes that extend for each setup. The setup cost pool would be allocated to products based on the number of setups or the time spent on setups, depending on the driver defined.
- A common misinterpretation is to treat setup overhead as a fixed cost per unit or per batch without considering the setup frequency, duration, or complexity. In ABC, using setups as the driver should reflect actual setup activity; otherwise, the $210 per setup hour may over- or under-allocate costs for products with different setup demands.

Overall consistency check:
- The two rates, 80 per machine hour and 210 per setup hour, imply distinct drivers for distinct cost pools and are plausible in an ABC framework where machining overhead scales with time on the machine, while setup overhead scales with the number or duration of setups. The key to their validity is that the chosen drivers (machine hours and setups) accurately reflect how each pool consumes costs in production.

If you had the underlying data, you would verify these numbers by: (a) summing each cost pool’s overhead, (b) summing the corresponding driver totals (total machine hours and total setups), and (c) dividing to obtain the rates, then rounding to the nearest dollar as required. Finally, you would apply these rates to each product using its actual machine hours and setup count to determine unit-level or batch-level costs.

Note: Since the problem statement provided the final numeric results for the two blanks, there are no multiple-choice options to evaluate here. The reasoning above reflects how one would arrive at and validate these ABC rates given complete cost and activity data.
