Passage for Q(4–6) :
In a field one summer’s day a Grasshopper was hopping about, chirping and singing to its hearts’s content. An Ant passed by, bearing along with great toil an ear of pea he was taking to the nest. “Why not come and chat with me, “ said the Grasshopper, “instead of to toiling and moling in that way ? ” “I am helping to lay up food for the winter,” said the Ant, “and recommend you to do the same.” “Why bother about winter?” said the Grasshopper ; “We have got plenty of food at present.” But the Ant went on its way and continued its toil. When the winter came the Grasshopper had no food an found itself dying of hunger – while it saw the ants distributing every day corn and grain from the stores they had collected int he summer. Then the Grasshopper knew : It is best to prepare for days of need
NSEJS Previous Papers 2013-2014 Ques No 4:
In the passage given above there seems to be a factural error with respect to the ant carrying the food to the nest.The most probable reason for this mistake would be
A. Pea pod is too heavy for an ant to carry to its nest.
B. Pea cannot be carried by an ant in the summber because it is a Rabi crop.
C. Ant couldn’t have passed by easily since it is the favourite food of grasshoppers.
D. Grasshoppers avoid coming out in summber and thus there cannot be grasshopper in the story.
NSEJS Previous Papers 2013-2014 Ques No 5:
What could be the most plausible reason that all the ants that toiled and moiled int he summer were
happy and content in the winter
A. Ants were probably happy since their food was not shared with Grasshopper
B. Ants need not worry to work anymore since they had food stocked.
C. Ants were happy since they enjoyed working together in summer.
D. Food that was procured was efficiently distributed and managed so that all the ants were fed equality.
NSEJS Previous Papers 2013-2014 Ques No 6:
Grasshopper was at fault in this story mostly because
A. Of its attitude towards ants who were working tirelessly
B. Of not having a forethought to store food for the upcoming winter season.
C. Of chirping and singing to its heart’s content in the summer
D. It should have asked ants for the food and managed to surpass the winter somehow.

Passage Q(16-18) :
Diatoms are the most common photosynthetic aquatic microorganisms group of algae which are unicellular and can exist as colonies in the shape of filaments or ribbons, fans, zigzags or stars depending on the quality of the water. Diatom communities are a popular tool for studies of water quality and pollution management. Karthik from Bangalore recently went on a field trip from Bangalore to Mysore. On the way he stopped his car at a sewage canal, a lake and a mountain stream and collected water samples from all the these places for his lab work. After a careful analysis of his water samples. he observed that diatoms came with varying size/shape and the size/shape increases has (have?) sometihing to do with the water quality
NSEJS Previous Papers 2013-2014 Ques No 16:
Below are the diatoms observed under a microscope by Karthik. Help him to recognise the correct order of sample localities (Viz., Canal, Stram and lake).
A. A-Mountain stream, B – Sewage Canal, C – Lake
B. A – Sewage Canal, B – Lake, C – Mountain Stream
C. A – Lake , B – Mountain stream, C – Sewage Canal
D. A – Mountain stream , B – Lake, C – Sewage canal
