Adrought in california created the opportunity for a quasi-experiment on the effectiveness of fines on water conservation (agras et al., 1980). three comparable cities were considered - two that instituted fines at different times and a third that did not. water consumption data for the 3 years before the onset of the fines were used as baseline and subsequent consumption data were gathered through the end of the drought. effectiveness of fines was assessed by examining consumption the following month. in this study, researchers capitalized on real-life opportunities to study phenomena. therefore, they maximized which type of validity?
a. statistical
b. construct
c. internal
d. external

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
