MCQ-> Read the following passage carefully and answer the questions given. Certain words/phrases have been given in bold to help you locate them while answering some of the questions.Inland waterways, as quiet as a mouse, keep the nation’s economy flowing as they transport $180 billion of coal, steel, chemicals and other goods each year across 38 states. Yet, an antiquated system of locks and dams threatens the timely delivery of those goods daily.Locks and dams raise or lower ships from one water level to the next, but breakdown of these carriers are frequent. The outage, which began last July, and is expected to end this August, will cost the power generation company and its customers $5.5 million as the utility ferries coal and other supplies along the river for itself and other businesses. As the economy picks up, the nation’s creaking infrastructure will increasingly struggle to handle the load. That will make products more expensive as businesses pay more for shipping or maneuver around roadblocks and it will cause the nation to lose exports to other countries both of which are expected to hamper the recovery. `The good news is, that the economy is turning,” says Dan Murray, Vice President of the Transportation Research Institute.“The bad news is we expect congestion to skyrocket,” he added. The ancient lockanddam system is perhaps the most egregious example of aging or congested transportation systems that are being outstripped by demand. Fourteen locks, out of the total twenty eight are expected to fail by 2020, costing the economy billions of dollars. Meanwhile, seaports cannot accommodate larger container ships, slowing exports and imports highways are too narrow. Bridges are overtaxed. The shortcomings were partly masked during the recession as fewer people worked and less freight was shipped, easing traffic on transportation corridors. But interviews with shippers and logistics companies showed that delays started lengthening along with the moderately growing economy. Yet there is little prospect for more infrastructure investment as a divided Government battles about how to cut the $1.3 trillion deficit and State and Local Governments face their own budget shortfalls. Government investment in highways, bridges, water systems, schools and other projects has fallen each year since 2008. IHS Global Insight expects such outlays to drop by 4.4% this year and 3% in the next year. According to experts, the country is spending about half of the $2.2 trillion that it should over a five year period to repair and expand overburdened infrastructure.Which of the following is TRUE in the context of the passage and according to the author?

MCQ-> Analyse the following passage and provide appropriate answers for the questions that follow: An effective way of describing what interpersonal communication is or is not, is perhaps to capture the underlying beliefs using specific game analogies. Communication as Bowling: The bowling model of message delivery is probably the most widely held view of communication. I think that’s unfortunate. This model sees the bowler as the sender, who delivers the ball, which is the message. As it rolls down the lane (the channel), clutter on the boards (noise) may deflect the ball (the message). Yet if it is aimed well, the ball strikes the passive pins (the target audience) with a predictable effect. In this one - way model of communication, the speaker (bowler) must take care to select a precisely crafted message (ball) and practice diligently to deliver it the same way every time. Of course, that makes sense only if target listeners are interchangeable, static pins waiting to be bowled over by our words - which they aren’t. This has led some observers to propose an interactive model of interpersonal communication. Communication as Ping - Pong: Unlike bowling, Ping - Pong is not a solo game. This fact alone makes it a better analogy for interpersonal communication. One party puts the conversational ball in play, and the other gets into position to receive. It takes more concentration and skill to receive than to serve because while the speaker (server) knows where the message is going, the listener (receive) doesn’t. Like a verbal or nonverbal message, the ball may appear straightforward yet have a deceptive spin. Ping - Pong is a back - and - forth game; players switch roles continuously. One moment the person holding the paddle is an initiator; the next second the same player is a responder, gauging the effectiveness of his or her shot by the way the ball comes back. The repeated adjustment essential for good play closely parallels the feedback process described in a number of interpersonal communication theories. Communication as Dumb Charades The game of charades best captures the simultaneous and collaborative nature of interpersonal communication. A charade is neither an action, like bowling a strike, nor an interaction, like a rally in Ping - Pong. It’s a transaction. Charades is a mutual game; the actual play is cooperative. One member draws a title or slogan from a batch of possibilities and then tries to act it out visually for teammates in a silent mini drama. The goal is to get at least one partner to say the exact words that are on the slip of paper. Of course, the actor is prohibited from talking out loud. Suppose you drew the saying “God helps those who help themselves.” For God you might try folding your hands and gazing upward. For helps you could act out offering a helping hand or giving a leg - up boost over a fence. By pointing at a number of real or imaginary people you may elicit a response of them, and by this point a partner may shout out, “God helps those who help themselves.” Success. Like charades, interpersonal communication is a mutual, on - going process of sending, receiving, and adapting verbal and nonverbal messages with another person to create and alter images in both of our minds. Communication between us begins when there is some overlap between two images, and is effective to the extent that overlap increases. But even if our mental pictures are congruent, communication will be partial as long as we interpret them differently. The idea that “God helps those who help themselves’ could strike one person as a hollow promise, while the other might regard it as a divine stamp of approval for hard work. Dumb Charade goes beyond the simplistic analogy of bowling and ping pong. It views interpersonal communications as a complex transaction in which overlapping messages simultaneously affect and are affected by the other person and multiple other factors.The meaning CLOSEST to ‘interchangeable’ in the ‘Communication as Bowling’ paragraph is:

MCQ->A medical clinic tests blood for certain disease from which approximately one person in a hundred suffers. People come to the clinic in group of 50. The operator of the clinic wonders whether he can increase the efficiency of the testing procedure by conducting pooled tests. In the pooled tests, the operator would pool the 50 blood samples and test them altogether. If the polled test was negative, he could pronounce the whole group healthy. If not, he could then test each person’s blood individually. The expected number of tests the operator will have to perform if he pools the blood samples are:...
