(a) How many entities are shown by this relation?
(b) What is the primary key of relation? (Hint: Flight# is unique; flight numbers do not repeat as they do on commercial airlines with regularly scheduled flights. Each flight will go to many villages and over time a village can receive many flights.)
(c) Give a example of one insertion anomaly present in this relation.
(d) Give a example of one deletion anomaly present in this relation.
(e) Is this relation in first, second, or third normal form? Why?
