The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: For users, Facebook's revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next? For the owners of the affected accounts, and of another 40 million that Facebook considered at risk, the first order of business may be a simple one: sign back into the app. Facebook logged everyone out of all 90 million accounts in order to reset digital keys the hackers had stolen - keys normally used to keep users logged in, but which could also give outsiders full control of the compromised accounts.  Which of the following points do not capture the negligence of Facebook in the most appropriate manner? Arguments: I. What Facebook knows so far is that hackers got access to the 50 million accounts by exploiting three distinct bugs in Facebook's code that allowed them to steal those digital keys, technically known as ‘access tokens’. The company says it has fixed the bugs.  II. The hack is the latest setback for Facebook during a tumultuous year of security problems and privacy issues . So far, though, none of these issues have significantly shaken the confidence of the company's 2 billion global users.  III. One of the bugs was more than a year old and affected how the ‘View As’ feature interacted with Facebook's video uploading feature for posting ‘happy birthday’ messages. But it wasn't until mid-September that Facebook noticed an uptick in unusual activity, and not until this week that it learned of the attack.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. It is widely known that the use of social media affects mental health, but a new, three-year study has found that it is the lack of sleep from its use and the psychological distress caused by cyberbullying via the platforms that are the main reasons affecting one’s state of mind, more than use of the actual apps. P. Girls who were checking social media also reported to be less happy and more anxious; however, boys didn’t report the same feelings. Q. In girls, the researchers said, the negative effects were due to disrupted sleep, cyberbullying and to some extent, lack of exercise. R. Researchers found that girls and boys who checked social media sites more than thrice a day had poorer mental health and greater psychological distress. S. In boys, the same three factors — disrupted sleep, cyberbullying, lack of exercise — had an effect too, but it was much smaller. 6. Dr Dasha Nicholls, from Imperial College London, who was also involved in the study added, “It’s not the amount of social media, per se, it’s when it displaces real-life contact and activities. It’s about getting a balance.”
