The contract was given to Sobha Singh (later Sir Sobha Singh). Construction really began after World War I and was completed by 1931.

Please answer this: Given the following passage  "Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.",  answer the following question. Note that the answer is present within the text.  Question: Who works with the DBMS interface?
++++++++
Answer: end-users


Please answer this: Given the following passage  "Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks. Variation in plumage also allows for the identification of birds, particularly between species. Visual communication among birds may also involve ritualised displays, which have developed from non-signalling actions such as preening, the adjustments of feather position, pecking, or other behaviour. These displays may signal aggression or submission or may contribute to the formation of pair-bonds. The most elaborate displays occur during courtship, where "dances" are often formed from complex combinations of many possible component movements; males' breeding success may depend on the quality of such displays.",  answer the following question. Note that the answer is present within the text.  Question: How do birds communicate indirectly?
++++++++
Answer:
preening, the adjustments of feather position, pecking, or other behaviour
