This questionnaire, and in fact all known efforts to prepare price indices for military R 6, D, have dealt solely with a set of inputs to the R & D activity, In the case of other objects of military expenditure, price indices and parities deal with kinds of output - personnel or maintenance services, weapons and equipment, facilities, etc. Although these are not yet an ideal kind of final output, such as “capability to exert military force”, they are one step removed and represent intermediate kind of output with inputs of their own. In the case of R & D, there is no comparable intermediate output in common use that can serve the same purpose. Indices and parities based on prices of inputs that are twice removed from the main output, military force, are less valid for comparison purposes. This is especially true for cross-national comparisons - namely, purchasing power parities - because the same set of inputs may be applied with widely differing productivity and represent dif ferinq “output” in different countries.

**Analysis**
The text appears to be discussing the expenditures and inputs of military research and development (R&D) in 1982. The categories mentioned, such as personnel, current expenditures, equipment, and construction, suggest that the focus is on the economic and financial aspects of military R&D. The text also highlights the challenges of preparing price indices and parities for military R&D, which further supports the idea that the category is related to economics.
