MCQ-> Analyse the following caselet and answer the questions that follow: Geetha Gawde can cultivate up to 6 crops a year. Crop A and B are ready for harvest in 2 months; crop C and D in 3 months, and crop E and F in 4 months. Crop A can be cultivated from January to June; crop B can be cultivated from April to September; crop C can be cultivated from May to December; crops D as well as E can be cultivated from August to December, and crop F from November to May. If Geetha plans a change of crop the soil should be left fallow for one month; however, if the same crop is sown no fallow time is needed. Sowing takes place only at the beginning of a month. Geetha can only harvest a maximum of 1000 units of any crop at any point in time. The production cost per unit (incurred at the time of sowing) and price per unit of crop are as follows:

For Geetha soil preparation does not incur any cost. If a crop is abandoned before the scheduled harvesting, she gets no money. Geetha is preparing a cropping schedule to maximize her annual profits (i.e. price – cost). She plans to replicate the schedule in the coming years.Which of the following would DEFINITELY be a part of the ideal schedule?

MCQ-> Read the following passage carefully and answer the questions given below it.Certain words/phrases have been printed in bold to help you locate them while answering some of the questions.Princess Chandravati was very beautiful. She loved all kinds of ornaments and always wanted to wear the most precious and lovely jewels. Once, a jeweller came to the palace and gifted the king a wonderful diamond necklace. It glittered with big and small diamonds. It was certainly a very expensive necklace. The princess fell in love with it as soon as she saw it. So the king presented it to her. From that day on, the princess always wore that necklace, wherever she went. One day before going for a swim in the pond, she took the necklace off and put in the hands of her oldest and the most trustworthy servant. “Hold this and be careful. This is the most precious necklace in the whole world,” she said. The servant was an old woman. She sat under a tree, holding the ornament tightly and waited for the princess. It was a hot afternoon and the servant was very tired so she dozzed off .under the tree. Suddenly the servant felt that someone was tugging at the necklace and she woke up with a start. She looked around but no one was there and the necklace was gone. Scared out of her wits, the old servant started screaming. On hearing her scream the royal guards rushed to her. She pointed towards the direction in which the thief may have gone and the guards ran off that way. There was a poor and dim-witted farmer walking on the same road. As soon as he saw the royal guards running towards him, he thought that they wanted to catch him and started running. But he was not a strong man and could not outrun the hefty guards. The royal guards caught him in no time. “Where is it ?” they demanded, shaking him. “Where is what ?” the poor farmer stammered back. “The necklace you stole 1” thundered one of the royal guards. The farmer had no idea what they were talking about. He only understood that some precious necklace was lost and he was supposed to have it. He quickly replied, “I don’t know where it is now. I gave it to my landlord.” The guards ran towards the landlord’s house. “Give us the necklace right now !” the guards demanded of the fat landlord. “Necklace ? I don’t have any !” the stunned landlord replied. “Then tell us quickly who does,” demanded the soldiers. In order to get the royal guards off his back, the landlord pointed towards a priest who was walking by his house and said, “He does.” The guards now caught hold of the priest who was walking towards the temple and thinking about the lunch he had just eaten. The priest was stunned when one of the burly guards jumped on him and asked about the necklace. He remembered that the minister, Bhupati, was at the temple. He took the guards to the temple and pointed towards the praying minister, “I gave it to him,” he said. Bhupati too was caught and all four men were thrown in jail. The chief minister of the kingdom knew Bhupati well and was sure that Bhupati would never steal. He decided to find out who the culprit was. He hid near the jail where all four men were put and heard them talking. First, Bhupati asked the priest, “Panditji, why did you say that you gave the necklace to me ? I was quietly praying at the temple and now you have landed me in jail for no fault of mine.” The priest looked apologetic. He pointed towards the landlord and said, “I didn’t know what to say. He set the guards on me. I was simply passing by his house and was on my way to the temple.” The land lord looked at the priest sheepishly. Then he turned towards the poor farmer and yelled, “You lazy good-for-nothing man Why did you say that I had the necklace ?” The farmer, trembling under the angry gaze of all three men, said, “I was just walking home, The guards caught me and I did not know what to say.” On hearing, this conversation, the chief minister understood that all the four men were innocent. He immediately ordered the royal guards to search thoroughly, near the pond. The guards searched high and low till they saw something glinting on the tree. On the tree sat a monkey with the princess’ favourite necklace around his neck. It took a lot of coaxing and bananas before the monkey threw the necklace on the ground. The king apologised to all the four men and gave them gold coins as compensation. He requested his daughter to wear the necklace only indoors.Why did the king present the diamond necklace to his daughter ?

MCQ-> The passage below is accompanied by a set of six questions. Choose the best answer to each question. During the frigid season... it's often necessary to nestle under a blanket to try to stay warm. The temperature difference between the blanket and the air outside is so palpable that we often have trouble leaving our warm refuge. Many plants and animals similarly hunker down, relying on snow cover for safety from winter's harsh conditions. The small area between the snowpack and the ground, called the subnivium... might be the most important ecosystem that you have never heard of.The subnivium is so well-insulated and stable that its temperature holds steady at around 32 degree Fahrenheit (0 degree Celsius). Although that might still sound cold, a constant temperature of 32 degree Fahrenheit can often be 30 to 40 degrees warmer than the air temperature during the peak of winter. Because of this large temperature difference, a wide variety of species...depend on the subnivium for winter protection.For many organisms living in temperate and Arctic regions, the difference between being under the snow or outside it is a matter of life and death. Consequently, disruptions to the subnivium brought about by climate change will affect everything from population dynamics to nutrient cycling through the ecosystem.The formation and stability of the subnivium requires more than a few flurries. Winter ecologists have suggested that eight inches of snow is necessary to develop a stable layer of insulation. Depth is not the only factor, however. More accurately, the stability of the subnivium depends on the interaction between snow depth and snow density. Imagine being under a stack of blankets that are all flattened and pressed together. When compressed, the blankets essentially form one compacted layer. In contrast, when they are lightly placed on top of one another, their insulative capacity increases because the air pockets between them trap heat. Greater depths of low-density snow are therefore better at insulating the ground.Both depth and density of snow are sensitive to temperature. Scientists are now beginning to explore how climate change will affect the subnivium, as well as the species that depend on it. At first glance, warmer winters seem beneficial for species that have difficulty surviving subzero temperatures; however, as with most ecological phenomena, the consequences are not so straightforward. Research has shown that the snow season (the period when snow is more likely than rain) has become shorter since l970. When rain falls on snow, it increases the density of the snow and reduces its insulative capacity. Therefore, even though winters are expected to become warmer overall from future climate change, the subnivium will tend to become colder and more variable with less protection from the above-ground temperatures.The effects of a colder subnivium are complex... For example, shrubs such as crowberry and alpine azalea that grow along the forest floor tend to block the wind and so retain higher depths of snow around them. This captured snow helps to keep soils insulated and in turn increases plant decomposition and nutrient release. In field experiments, researchers removed a portion. of the snow cover to investigate the importance of the subnivium's insulation. They found that soil frost in the snow-free area resulted in damage to plant roots and sometimes even the death of the plant.The purpose of this passage is to
