Read the following passage and answer the questions that follow: In 2009, swine flu spread quickly around the world, become dying down in 2010. This type of global outbreak is known as a pandemic. The virus was first identified in Mexico in April 2009. It spread rapidly from country to country because it was a new type of flu virus that few people had full resistance to. Like any other flu, swine flu is an extremely contagious viral infection spread through the air and impacts the respiratory system. Graph in figure 1 shows the generation time for influenza (the time from one infection to the next). On an average it is only 2 days. The typical incubation period (the time between infection and appearance of symptom) for influenza is 1-4 days. Adults shed influenza virus from the day before symptoms begin. The number of reported cases of swine flu in X country during last five years is depicted in On the basis of figure 1, after how many days of the onset, the infectivity decreases rapidly?

Read the following passage and answer the questions that follow: A researcher analyzed sample of ocean sediments from various depths, to collect information about the concentration of chemicals like ions of Sulphur and iron, and dissolved gases. He started from the top surface of the sediment or bottom of the sea level (0 cm). After laboratory analysis, he recorded observations as shown in the following table. He chose the unit of concentration as parts per million (ppm). Apart from chemicals he also estimated pH value to determine hydrogen ion concentration. Following scale represents the pH scale used to determine acidity of a solution. The concentration of which of the following is constant after depths of 10 cm or more?
