The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: The domestic equity market has become supervolatile  and converted the psychology of every market participant into fear. Greed and fear continue to alternate in the market, like the two sides of a coin. To a seasoned player, there seems to be nothing new as such instances of panic-selling often occur time and again. Why? Arguments: I. Since demonetisation, herd mentality had jacked up financials, banks and NBFC stocks to great heights on the pretext of financial inclusion and formalisation of the economy. This caused the financials gain disproportionate share in Nifty50 at 35 per cent of the free float market capitalisation, which was unheard of in the past.  II. The domestic market seems to be deeply oversold and can rebound on any good news. The Nifty50 has taken long-term support at the three-year trend line, which makes a case for the correction to near its end. III. Investors, therefore, should not panic and sell off shares. Instead they should do the reverse and gather the courage to pump in more money into the market by picking quality stocks or investing in ETFs for more stable returns.

Ants have been living on the earth for more than 100 million years and can be found almost anywhere on the planet. It is estimated that there are about 20000 different species of ants. For this reason ants have been called Earth's most successful species. If you watch ants for any length of time you will see that they really do communicate with each other and very effectively too. Ants communicate by touching each other with their antennae. Ants also use chemicals called pheromones to leave scent trails for other ants to follow. Ants build many different types of homes. Many ants build simple little mounds out of dirt or sand. Other ants use small sticks mixed with dirt and sand to make a stronger mound that offers protection from rain. Western Harvester ants make a small mound on top, but then tunnels up to 15 feet straight down to hibernate during winter. Ant mounds consist of many chambers connected by tunnels. Different chambers are used for nurseries, food storage, and resting places for the worker ants. Some ants live in wood like termites. Army ants don't make a home at all but travel in a large groups searching for food. Ants are social insects which means they live in large colonies or groups. Some colonies consist of millions of ants. There are three types of ants in each species, the queen, the sterile female workers and males. The male ants only serve one purpose, to mate with future queen ants and do not live very long. The queen grows to adulthood, mates, and then spends rest of her life laying eggs. A colony may have only one queen, or there may be many queens depending on the species. Ants go through four stages of development: egg, larva, pupa and adult.
