Match List - I and List - II and select the correct answer from the codes given below: Codes:List - I List - II a. Flood 1. Lack of rainfall of sufficient duration b. Drought 2. Tremors produced by the passage of vibratory waves through the rocks of the earth c. Earthquake 3. A vent through which molted substances come out d. Volcano 4. Excess rain and uneven distribution of water
a-4, b-1, c-2, d-3
Matching questions are quickest to solve by pairing whichever items are unmistakable first, then using the codes to eliminate.
Item a, Flood, matches description 4, excess rain and uneven distribution of water. A flood is the submergence of normally dry land, caused most often by rainfall exceeding what rivers and drainage can carry away.
Item b, Drought, matches description 1, lack of rainfall of sufficient duration. Drought is the opposite condition, a prolonged shortfall of precipitation leading to water scarcity, crop failure and, in severe cases, famine. Note that duration is what distinguishes drought from a merely dry spell.
Item c, Earthquake, matches description 2, tremors produced by the passage of vibratory waves through the rocks of the earth. When accumulated stress along a fault is released, seismic waves travel outward through the rock and shake the surface.
Item d, Volcano, matches description 3, a vent through which molten substances come out. A volcano is an opening in the crust through which magma, ash and gases escape, magma being called lava once it reaches the surface.
The combination is therefore a-4, b-1, c-2, d-3, which is the first code.
A quick way to reach the same place is to notice that Flood and Drought are the two water related items and must take descriptions 4 and 1 between them. Only the first and fourth codes give Flood the value 4, and the fourth code then assigns Drought to 3, the volcanic vent, which is plainly wrong. That leaves the first code without any need to check the remaining pairs.
Hence the correct match is a-4, b-1, c-2, d-3.
