31 option A) Equator, Tropical Wet/Dry is found near the equator, usually on the outer edges of Tropical Wet climate areas. The largest areas of Tropical Wet/Dry are found in Africa, Brazil, and India. 

32.option C) the tropics,  half of the world's population, about 3.6 billion people in 2013, During the growing season in the temperate region, receive more solar radiation during their cropping season than most tropical rainy the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter. The word "tropical" sometimes refers to this sort of climate rather than to the geographical zone. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone.

The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. As of 2014, the region was home to 40% of the world's population, and this figure was then projected to reach 50% by 2050.

33.option B) Convectional, The most powerful force which causes air to rise and cool is the Sun. When the Sun heats the surface of the Earth, warming of the air above the ground takes place. This warm air rises and cools as it goes higher. At a certain point, condensation will occur and clouds will form. If the air is humid, the cloud base will be low. The size and shape of convection clouds depends on the humidity of the rising air and the strength of the convection. Convection clouds are made up of millions of suspended water droplets that have condensed from water vapour. But not all convection clouds release rain. Convection clouds are cumulus clouds which can range from the 'fluffy white cotton wool ball' clouds to the towering cumulonimbus thunder clouds. The fluffy cumulus clouds are known as fair weather clouds. These rarely produce any rainfall. Larger 'cauliflower-like' cumulus clouds may produce light showers, whilst the cumulonimbus clouds can produce heavy downpours and thunderstorms.

34.option C) cP air meets mT air in the vicinity of a low pressure center ,  If the upper levels are favorable, then the mid-latitude cyclone will continue to develop and bring up mT air in the warm sector and bring down cP air in the cold sector.

a.     The mT air rises as it moves out ahead of the low helping to deepen the Low pressure center to the east and help it move along

b.    The cP air sinks behind the system and fills in the Low on the backside also helping to move the system along.

35.option A) Tropical, Tropical diseases are diseases that are prevalent in or unique to tropical and subtropical regions.^[1] The diseases are less prevalent in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation. However, many were present in northern Europe and northern America in the 17th and 18th centuries before modern understanding of disease causation. The initial impetus for tropical medicine was to protect the health of colonial settlers, notably in India under the British Raj.^[2] Insects such as mosquitoes and flies are by far the most common disease carrier, or vector. exotic diseases in the tropics have long been noted both by travelers, explorers, etc., as well as by physicians. One obvious reason is that the hot climate present during all the year and the larger volume of rains directly affect the formation of breeding grounds, the larger number and variety of natural reservoirs and animal diseases that can be transmitted to humans (zoonosis), the largest number of possible insect vectors of diseases. It is possible also that higher temperatures may favor the replication of pathogenic agents both inside and outside biological organisms. Socio-economic factors may be also in operation, since most of the poorest nations of the world are in the tropics. Tropical countries like Brazil, which have improved their socio-economic situation and invested in hygiene, public health and the combat of transmissible diseases have achieved dramatic results in relation to the elimination or decrease of many endemic tropical diseases in their territory.
