You marked two ink-spots along the height at the base of a coconut tree and also at the top of the tree. When
you examine the spots next year when the tree has grown taller, your will see-

(B) the top two spots have grown less apart then the bottom two spots
(C) both sets of spots have grown apart to the same extent
(D) both sets of spots remain un-altered
Students attend our lectures, not because the mathematics we teach ‘makes lots of fun’ for us, but because they believe they can learn some essential knowledge from us. And each of our young students has only one life to live. We should therefore be a
