(25 points) Questionl Consider the following instance of the Students relation, sorted by age. Assume that these tuples are stored in a sorted file in the order shown; the first tuple is on page 1, the second tuple is also on page 1; and so on. Each page can store up to three data records; so the fourth tuple is on page 2. Explain the data entries that each of the following indexes contain. If the order of entries is significant, say so and explain why. If such an index cannot be constructed, explain why login sid name 53831 Madavan madavanmusic 11.8 53832 GuldugulduOmusic 53666 Jones 53688| Smith ?smith@ee 53650 Smith agegpa 12 2.0 18 3.4 19 3.2 19 3.8 jonescs smith@math .
