The root word that we are able to extract from the given sentence is protracted.
The word means lasting for sometime longer than the original or originally set plan. In the context of the given item, the meaning of protracted conversation would be long and involved. Thus, the answer to this item is the 1st choice.
1- <span>The ancient Chinese board game “Go” is invented long before there was any writing to record its rules. A game from the impossibly distant past has now brought us closer to a moment that once seemed part of an impossibly distant future: a time when machines are cleverer than we are.
<u>Because it's an action that started and finished in the past, this should read </u><u>was</u><u> (Simple Past)</u>
2- </span><span>For years, Go was considered the last redoubt against the march of computers. Machines might win at chess, draughts, Othello, three-dimensional noughts and crosses, Monopoly, bridge, and poker. Go, though, is different.
<u>This continues the same line of mistake as the first paragraph. Because it's referencing something that already happened ("Go was considered...), this should read </u><u>was</u><u> (Simple Past).</u>
The game required intuition, strategising <u>and</u> character reading, along with vast numbers of moves and permutations. According to legend, it was invented by a Chinese emperor to teach his subjects balance and patience: qualities unique to human intelligence.
<u>The conjunction and is used before the last element in a list. In this case, this word should be substituted by a comma because <em>character reading</em> is not the last element on that list.</u>
3- </span><span>This week, though, a computer called Alpha Go <u>defeats</u> the world’s best player of Go. It did so by “ learning” the game, crunching through 30 million positions from recorded matches, reacting and anticipating. It <u>evolves</u> as a player and taught itself.
That single game of Go marks a milestone on the road to the “technological singularity”, the moment when artificial intelligence becomes capable of self-improvement and learns faster than humans can control or understand.</span><span>
<u>These should read defeated ... evolved. This continues the same line of thought on subject-verb agreement. If it's talking about a past event, and the rest of the paragraph sustains that idea, then these verbs should be in Simple Past.</u></span><span>

The detail that supports an argument that technology brings some teens together because it improves their social lives is “[f]ifteen to 30 percent of teens . . . reported feeling less shy, more outgoing, more self-confident, more popular”.
The paragraph starts with the topic, first, it refers to teens who do not feel social networks change their social lives. Second, it refers to those who claim social media has a positive effect on their social lives and, finally, it refers to those teens who feel social media has a negative impact on their lives.
The sentence “[f]ifteen to 30 percent of teens . . . reported feeling less shy, more outgoing, more self-confident, more popular” belongs to the second aspect described. That is to say, it is supporting the claim about the positive impact of social media in teens' lives.
The other options are not correct because the first one is the topic sentence, and the last option is a negative effect of social networks on teens' lives.
