Direction: Read the following passages carefully and answer the question that follows.
We know that gold and silver are elements. An element consists of atoms of only one kind, unlike water, which consists of both hydrogen and oxygen. Another element is radium. Radium is especially interesting, because it produces heat, When soil is carried by rivers down to the sea and falls to the bottom, it often carries radium in it. As more and more soil is washed down into the ocean. more and more radium is carried in it. There, as elsewhere, it constantly produces heat.
Q. Some heat on the ocean floor comes from?

Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.
In a country where more than 400 million people live without electricity, it isn't political rhetoric and policies filtered through many layers of bureaucracy that will benefit people. An innovative approach to identifying and addressing the basic lack of infrastructure works best. This is best exemplified by the initiative to convert rice husks into electricity in Bihar. Pioneered by a company called Husk Power Systems, established in 2007, by Bihar native Gyanesh Pandey along with three partners- it's a peculiarly Indian initiative, making a virtue out of the necessity of low-cost solutions to large scale problems. In essence, Pandey and his partners have devised an electric distribution system powered by the waste product of rice husks, generated when rice is milled- something in abundant supply in Bihar where, it is estimated, 1.8 billion kg of rice husk are produced annually

Direction: Read the following passage and answer the questions based on it.
Honest self-criticism plays a vital role to purify our souls and to light the path of blissful success. The Holy Quran says: Truly he has succeeded who purifies it. And Truly, he has failed who defiles it. In fact, self criticism seems like a fairly straight-forward concept. It means acknowledging that we have committed a sin, whether against ourselves or other, be it Our Creator or anyone or anything in creation. For most of us, such a confession is an incredibly tough thing to do. Pride prevents us from owning our faults, especially before people when it is necessary. It behoves us to recall that being honest with ourselves is actually a way to enjoy life, rather than make it tougher. It is a fact that the best way to prevent ourselves from committing haram acts is to really investigate whether or not such activities are permissible in Islam and to refrain from doing them if they are not permissible
Q. What does self-criticism mean in this passage ?
