Question

as breaking news unfolds people increasingly rely on social media to stay abreast of the latest updates. (2) the use of social media in such situations comes with the caveat that new information being released piecemeal may encourage rumors, many of which remain unverified long after their point of release. (3) little is known however about the life cycle of a social media rumor. (4) in this paper we present a methodology that has enabled us to collect, identify and annotate a dataset of 330 rumor threads (4,842 tweets) associated with 9 newsworthy events. (5) we analyze this dataset to understand how users spread, support, or deny rumors that are later proven true or false, by distinguishing two levels of veracity in a rumor life cycle i.e., before and after its status is resolved. (6) the identification of rumors associated with each event. (7) as well as the tweet that resolved each rumor as true or false. (8) was performed by journalist members of the research team who tracked the events in real time. (9) our study shows that rumors that are ultimately proven true tend to be resolved faster than those that turn out to be false.

short answer: correct the punctuation in sentence 3.

Explanation:

1. Analyze the context of sentence 1 to find a word - substitute. "abreast" in the context means being well - informed or keeping up with information. "educated" is the most appropriate as it implies having knowledge.
2. For sentences 6 - 8, re - structure for better grammar and readability. The original sentence is convoluted. The correct re - write is "The identification of rumors associated with each event, as well as the tweet that resolved each rumor as true or false, was performed by journalist members of the research team who tracked the events in real time."

Answer:

1. C. educated
2. The identification of rumors associated with each event, as well as the tweet that resolved each rumor as true or false, was performed by journalist members of the research team who tracked the events in real time.
