The four sentences (labelled 1, 2, 3 and 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.1. Billions of years ago, shifts in atmospheric composition like the impact of photosynthetic life set precedents for major climatic changes.2. Sustained volcanic activity, driven by the movement of Earth's tectonic plates, can alter regional and global climates by modifying ocean currents and wind patterns.3. The Earth's climate evolves due to interactions between the atmosphere and various geological, chemical, biological, and geographical factors.4. Human beings significantly impact climate change by emitting greenhouse gases into the atmosphere; however, this is just one part of a complex equation.

The four sentences (labelled 1, 2, 3 and 4) given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.1. Some places, such as the southwest of the US, now in its 24th year of drought, may have switched permanently to a drier state.2. In general, the dry parts of the world are becoming drier, partly through reduced rainfall and partly through declining river flow.3. Rising temperatures cause increased evaporation and increased transpiration by plants and add to this problem.4. Many of the world’s major growing regions are now threatened by “flash droughts”, in which hot and dry weather sucks moisture from the soil at frightening speed.

Five sentences related to a topic are given in the question below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out. Choose its number as your answer and key it in.But he has also accelerated the transference of phosphorus from plant and animal life to the sea, thus speeding up its cyclical migration in a two-fold manner.With the development of agriculture in historic times, however, the phosphorus cycle has been seriously upset, for systematic cropping reduces the reserves in the soil more quickly than they can be renewed from fresh sources.For some time after the earth's formation, the phosphorus cycle in the sea was simple, phosphate ions built up into the earliest forms of organic life and released again at their death.Furthermore, the emergence of life from the sea and the colonization of dry land led to a soil-plant-animal-soil cycle, from which phosphorus was removed in negligible quantities in the formation of bone beds, fossil fish or guano deposits.In the past few centuries man has attempted to restore the phosphorus balance by the use of fertilizers, derived largely from natural deposits.
