MCQ-> The CEO of ABC Telecom Ltd. (ABC) is in a quandary since he received the telephone call in the morning from his counterpart at LMN Telecom Ltd. (LMN). Both companies were engaged in a bitter experience a couple of years ago when they had attempted to merge with the intention of creating a behemoth telecom company, possibly the largest in the world. The merger had fallen through due to opportunistic behavior on the part of Mr. Das, then CEO of LMN. During the time the merger talks were taking place, Mr. Das had also approached a few other suitors for LMN in an attempt to force ABC to pay a higher price. Further, there were reports of attempts by management of LMN to scuttle the deal. Back then, ABC had also faced stiff opposition to the deal from one of its large shareholders. Since then, a lot has changed for both companies. The bleak economic conditions due to recession had led to a drastic fall in the market value of both companies, with ABC comparatively losing much more in terms of market value. Raising money has become more difficult for both companies, especially for LMN. On the brighter side for ABC, the opposing shareholder had recently sold off his stake to another investor who earlier had supported the original merger deal with LMN a couple of years ago.Which of the following would be the most appropriate line (s) of thought for the CEO of ABC to adopt in response to the offer by LMN? I. Once bitten twice shy. There is simply no way I can think of resuming talks with LMN after their unethical behaviour the previous time around. I would rather spend my time on merger discussions with other companies. Ii. The deal may make less business sense this time around. However, if it goes through, I will become the CEO of the world’s largest telecom company. So let us try our luck once more. Iii. I will resume talks only if they provide guarantees as to the reimbursement of our expenses incurred, in the event of the deal not materializing. Iv. Let me not be biased against dealing with LMN, if we can secure the deal at a reasonably low price, benefiting our shareholders, let us go ahead with it. V. I am not sure if we can raise the money now. In any event, they are the ones facing greater financial problems. So let’s not hurry now. We might have an opportunity to buy them out at a cheaper price later.....

MCQ-> Read the following passage carefully and answer the questions given below it. Certain words are given in bold to help you answer some of the questions.At the heart of what makes India a better regime than China is a healthy respect for the civil rights and liberties of its citizens. There are checks and balances in our government. But India’s new surveillance programme, the Central Monitoring system (CMS), resembles a dystopian society akin to George Orwell’s 1984.According to several news reports, the CMS gives the government, Indian security agencies and income tax (IT) officials the authority to listen to, and tape phone conversions, read emails and text messages, monitor Posts on Facebook, Twitter or Linkedin and track searches on Google of selected targets, without oversight by the courts or parliament. To call it sweeping is an understatement.Typically, Indian Security agencies need a court order for surveillance, or depend on Internet/telephone service providers for data, provided they supply a warrant. CMS allows the government to bypass the court. Milind Deora, India’s Minister of State for Information Technology says the new system will actually improve citizens’ privacy because telecommunication agencies would no longer be directly involved in the surveillance; only government officials would have these details – missing the point that in a democracy, there has to be freedom from government surveillance. This is hardly comforting in a nation riddled with governmental corruption.India does not have a privacy law. CMS will operate under the Indian Telegraph Act (ITA). The ITA is a relic of the British Raj from 1885, and gives the government the freedom to monitor private conversations. News reports quote anonymous telecommunications ministry officials as saying that CMS has been introduced for security purposes, and “this is to protect you and your country”.That is irrational. For one, there are no ‘security purposes’ that prevent the government from having a rational debate on this programme and getting approval from our elected representatives before authorizing such wide-reaching surveillance. If the government is worried that a public debate in a paralysed parliament would half the programme’s progress, then it can convene a committee of individuals or an individual body such as CAG to oversee the programme. It can seek judicial approval from the Supreme Court, and have a judge sign off on surveillance requests without making these requests public.As of now, the top bureaucrat in the interior ministry and his/her state level deputies will have the power to approve surveillance requests. Even the recently revealed US surveillance Programme, had ‘behind the doors’ bipartisan surveillance approval. Furthermore, US investigation agencies such as the CIA and NSA are not the ruling party’s marionettes; in India, that the CBI is an arm of the government is a fait accompli. Even the Supreme Court recently lambasted the CBI and asked it to guarantee its independence from government influences after it was proved that it shared unreleased investigation reports with the government.There is no guarantee that this top bureaucrat will be judicious or not use this as a tool to pursue political and personal vendettas against opposition parties or open critics of the government. Security purposes hardly justify monitoring an individual’s social media usage. No terrorist announces plans to bomb a building on Facebook. Neither do Maoists espouse Twitter as their preferred form of communication.Presumably, security purposes could be defined as the government’s need to intercept terrorist plans. How does giving the IT department the same sweeping surveillance powers justify security purposes? The IT office already has expansive powers to conduct investigations, summon individuals or company executives, and raid premises to catch tax evaders. In a world where most financial details are discussed and transferred online, allowing the IT departments to snoop on these without any reasonable cause is akin to airport authorities strip searching everyone who boards a flight.What happened on 26/11 or what happens regularly in Naxal – affected areas is extremely sad and should ideally, never take place again. But targeting terrorists means targeting people who show such inclinations, or those who arouse suspicions, either by their travels or heir associations with militant or extremist groups. And in a country where a teenager has been arrested for posting an innocent comment questioning the need for a bandh on the death of a political leader, gives us reason to believe that this law is most likely to be misused, if not abused. Select the word which is MOST OPPOSITE in meaning to the word printed in bold, as used in the passage. AKIN....
