The three ways in which the working of Parliament is suspended or ended: adjournment (a short break in a sitting), prorogation (the end of a session), and dissolution (the end of the life of the Lok Sabha).
The adjournment-prorogation-dissolution sequence, who orders each, and the rule on lapsing of Bills are standard, easily tested parliament facts.
Adjournment is by the Presiding Officer, while prorogation and dissolution are by the President; the Rajya Sabha is never dissolved, unlike the Lok Sabha.
Adjournment (break in sitting, by chair), prorogation (end of session, by President), dissolution (end of Lok Sabha, by President); Rajya Sabha is permanent.
