MCQ-> Study the following information carefully and answer the questions given below:Eight friends P, Q, R, S, W, X, Y and Z are sitting around a circular table but not necessarily in the same order. Some of them are facing the centre and some others are facing outside (i.e. in a direction opposite to the centre.) Note :(i) Facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. (ii) Facing the opposite directions means if one person faces the centre then the other faces outside and vice-versa. (iii) Immediate neighbours facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. (iv) Immediate neighbours facing the opposite directions means if one person faces the centre then the other faces outside and vice-versa. • R sits second to the right of Y. Only two persons sit between R and W. • P sits to the immediate right of W. W faces outside. • Only one person sits between P and Z. Immediate neighbours of P face opposite directions. • Q sits third to the left of Z. Q is not an immediate neighbour of P. • X faces a direction opposite to that of Y. X is an immediate neighbour of neither Y nor P. • Immediate neighbours of S face same direction. P does not face outside. • R and Q face a direction opposite to that of S.Four of the following five are alike in a certain way based on the direction they are facing and so form a group. Which is the one that does not belong to that group?

MCQ-> Study the following information carefully and answer the questions given below: Eight friends — J, K, L, M, N, 0, P and Q — are sitting around a circular table but not necessarily in the same order. Some of them are facing the centre and some of them are facing outside. (i.e. in a direction opposite to the centre.) Facing the same direction means if one person faces the centre then the other also faces the centre and vice-versa. Facing the opposite direction means if one person faces the centre then the other faces outside and vice-versa. Immediate neighbours facing the same direction means if one neighbour faces the centre then the other also faces the centre and vice-versa. Immediate neighbours facing the opposite direction means if one neighbour faces the centre then the other faces outside and vice-versa. • Only one person sits between K and 0. Q sits third to the right of 0. • M sits to the immediate right of Q. Q faces outside. • L sits second to the left of P. P is not an immediate neighbour of 0. • L faces a direction opposite to that of 0. Immediate neighbours of L face opposite directions. • J sits third to the left of N. J is not an immediate neighbour of P nor K. • M and J face a direction same as that of N.Four of the following five are alike in a certain way based on the directions they are forming and so form a group.

MCQ-> Read the following passage and answer the questions. Passage: A new paper published by Rochman and her colleagues in February, in the journal Ecology, sifts through past research on marine debris to assess the true extent of the environmental threat. Plenty of studies have sounded alarm bells about the state of marine debris: Rochman and her colleagues set out to determine how many of those perceived risks are real Often. Rochman says, scientists will wrap up a paper by speculating about the broader impacts of what they've found. Maybe their study has shown that certain seabirds eat plastic bags, for example, and the paper goes on to warn that whole bird populations are at risk of dying out. "But the truth was that nobody had yet tested those perceived threats." Rochman says. "There wasn't a lot of information." Rochman and her colleagues examined more than a hundred papers on the impacts of marine debris that were published through 2013. Within each paper. they asked what threats scientists had studied-366 perceived threats in all and what they'd actually found. In 83 percent of cases, the perceived dangers of ocean trash were proven true. In most of the remaining cases. the working group found the studies too shoddy to draw conclusions from—they lacked a control group, for example. or used faulty statistics. Strikingly. Rochman says, only one well-designed study failed to find the effect it was looking for, an investigation of mussels ingesting microscopic plastic bits. The plastic moved from the mussels' stomachs to their bloodstreams. scientists found. and stayed there for weeks—but didn't seem to stress out the shellfish. A lot of ocean debris is "microplastic," or pieces smaller than five millimetres. These may be the beads from a facial scrub. fibres shed by synthetic clothing in the wash. or eroded remnants of larger debris. Compared to the number of studies investigating large-scale debris. Roclunan's group found little research on the effects of these tiny bits. There are also, she adds, a lot of open questions about the ways that ocean debris can lead to sea-creature death. Many studies have looked at how plastic affects an individual animal or that animal's tissues or cells, rather than whole populations. And in the lab, scientists often use higher concentrations of plastic than what's really in the ocean. None of that tells us how many birds or fish or sea turtles could die form plastic pollution or how deaths in one species could affect that animal's predators, or the rest of the ecosystem. "We need to be asking more ecologically relevant questions." Rothman says. Usually, scientists don't know how disasters like oil spills or nuclear meltdowns will affect the environment until after they've happened. she says. "We don't ask the right questions early enough." But if ecologists can understand how the slow-moving disaster of ocean garbage is affecting ecosystems. they might be able to prevent things from getting worse.Which ONE of the following conclusions based on the examination of the hundred-odd papers on marine debris and its ecological impact by Rachman and her colleagues is NOT CORRECT?
