Here we are providing you the important question of reasoning ability for the IBPS PO & Clerk Exam.
Q1-7 In the following passage there are blanks each of which has been numbered. These numbers are given below the passage and against each five words have been suggested, one of which fits the blanks appropriately. Find out the appropriate word in each case.
How does ticking clock work? Carbon appears widely in nature—in coal, vegetables, animals and all kinds of other (1) material. Importantly, it appears in a few different “isotopes”, or avatars. The everyday isotope—accounting for the great majority of carbon—is called Carbon 12, because each of its atoms contain six protons and six neutrons. But(2) amid all that C12 are tiny deposits of a mutant variety called Carbon 14, whose atoms have two extra neutrons.
Never mind what protons and neutrons are. What’s important is that because of the extra neutrons, the C14 atom (strictly, its nucleus, but never mind) is unstable and thus decays. That is, it steadily loses matter and energy by (3) certain kinds of sub-atomic particles. This decay process is called radioactivity.
C14 is formed high up in our atmosphere by cosmic rays. These are themselves atomic particles, zooming through the universe at great speed. Many enter the Earth’s atmosphere and it’s (4) that about half a million of them hit each of us humans each hour. But cosmic rays also (5) into high-flying nitrogen atoms and turn them into C14 atoms. (It’s a little more complicated, but, again, never mind). These atoms team up with oxygen and form carbon dioxide (CO2).
Plants absorb CO2, and that’s how they come to contain C14. Humans and other animals eat plants, which is how C14 turns up in our bodies. In fact, it’s in our bodies at about the same concentration—one part in a trillion (6) carbon, I did say “tiny deposits”—as it appears elsewhere.
When plants die, they suddenly stop absorbing C14. When we die, we suddenly stop eating plants, and therefore (7) C14. So, since C14 is radioactive and decays, the amount of C14 in any organic matter this drop in level of radioactive isotopes is the very foundation of radiocarbon dating. If we know the speed at which radioactive substances decay, we can use that to determine the age of an artefact that contains such substances.In the case of C14, we know that a given amount of it will reduce by half in about 5,700 years. This is called C14’s “half-life.
