The Prime Minister is central to the life of the Cabinet. Justify this statement by mentioning any four powers of the Prime Minister with reference to the Cabinet.

(1) He FORMS the Cabinet — he selects the ministers and recommends their names to the President, so no one can become a minister without his approval. (2) He ALLOCATES portfolios among the ministers and may reshuffle them at any time, moving a minister from one department to another. (3) He PRESIDES over the meetings of the Cabinet, fixes its agenda, guides its discussions and sums up its decisions; he co-ordinates the work of the different departments. (4) He can DISMISS the ministry — he may ask any minister to resign, and if he himself resigns the whole Council of Ministers falls with him, since there can be no Cabinet without a Prime Minister.

Four marks, four powers, one mark each. The verbs make the structure clear — forms, allocates, presides, dismisses. The question says "justify", so the fourth point is the strongest: the Cabinet is not merely led by him but DEPENDS on him, since his resignation dissolves the whole ministry. Quotable descriptions worth using: the Prime Minister is "the keystone of the Cabinet arch" and "primus inter pares" — first among equals.
