6. Read the following passage carefully and answer the questions given below:
A river is any natural stream of fresh water, larger than a brook or a creak, which flows in a well defined channel. Usually it discharges into another larger body of water: an ocean, a lake or another river. In rare instances, in regions of porous soil it soaks into the ground, or in excessively dry regions, evaporates, in which case it becomes a lost river. In other regions of favorable rock conditions it may also run underground for certain distance, disappearing and reappearing one or more times. A river with a well-cut channel and a graded bed, usually reaching base-level at its mouth, is an adolescent river. Rivers as they grow older usually widen their valleys accordingly, unless prevented by certain geological formations or occurrences. A river whose upper waters some time in the past suddenly found a new outlet, diminishing the volume and force of the original river and also its length, is known as a beheaded river. In general, the size of rivers depends on the geographical landscape, which ranges from the insignificant drainage areas of streams rising on high ground near the coast and flowing straight down to the sea, to immense parts of continents, where rivers rising on the slopes of mountain ranges far inland have to traverse vast stretches of valleys and plains before reaching the ocean.

Questions:
(a) The first sentence of this passage is one of the following:
i. a demonstration
ii. a comparison.
iii. a definition
iv. a narration.
(b) The writer specifically mentions three types of rivers. Name them.
(c) Which phrase tells you that the shape of the land affects the dimension of the river?
(d) In some cases a river dries up. Name the two conditions when this happens.
(e) Can a river become invisible at times? If yes, when?
(f) What factors obstruct the natural process of older rivers increasing their width?
(g) If part of a river suddenly changes its direction, how does it affect the entire river?
(h) Match the following: [1+2+1+2+1+2+2+5]
A B
(a) discharges 1. become smaller
(b) favorable 2. properly explained
(c) diminish 3. clearly marked
(d) well defined 4. disappear
