Questions

SQL statements are broadly classified into three. They are

1. DDL – Data Definition Language

DDL is used to define the structure that holds the data. For example, Create, Alter, Drop and Truncate table.

2. DML – Data Manipulation Language

DML is used for manipulation of the data itself. Typical operations are Insert, Delete, Update and retrieving the data from the table. The Select statement is considered as a limited version of the DML, since it can't change the data in the database. But it can perform operations on data retrieved from the DBMS, before the results are returned to the calling function.

3. DCL – Data Control Language

DCL is used to control the visibility of data like granting database access and set privileges to create tables, etc. Example - Grant, Revoke access permission to the user to access data in the database.

Since, the sentence starts talking about the leader of the opposition, the connecting statement will be R as it carries a relative pronoun ‘who’ which relates the sentences. S follows as it states the disappointment of the leader and the next statement talked about the reason of disappointment. P would be the concluding statement as it goes with the flow describing how the leader decided to convince the assembly and thus makes a coherent paragraph.

The correct formation would be, ‘The leader of the opposition who had a reputation for speech making was very much disappointed on realising that he had failed to convince the assembly in the manner he had planned to convince them’.
