 Note that a lot of the questions could have more than one correct answers. We only need a single most-likely answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.  

Sentence: His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. His father published a variety of works on the subject, several of which are still well known, especially his The Standard Elocutionist (1860), which appeared in Edinburgh in 1868. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. In this treatise, his father explains his methods of how to instruct deaf-mutes (as they were then known) to articulate words and read other people's lip movements to decipher meaning. Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. Bell became so proficient that he became a part of his father's public demonstrations and astounded audiences with his abilities. He could decipher Visible Speech representing virtually every language, including Latin, Scottish Gaelic, and even Sanskrit, accurately reciting written tracts without any prior knowledge of their pronunciation. 
Question: The Standard Elocutionist was printed how many times?
168

Sentence: In September 2014, Professor Stefan Grimm, of the Department of Medicine, was found dead after being threatened with dismissal for failure to raise enough grant money. The College made its first public announcement of his death on 4 December 2014. Grimm's last email accused his employers of bullying by demanding that he should get grants worth at least £200,000 per year. His last email was viewed more than 100,000 times in the first four days after it was posted. The College has announced an internal inquiry into Stefan Grimm's death. The inquest on his death has not yet reported. 
Question: How many times was Professor Stefan Grimm's email viewed in the first four days after it was posted online?
more than 100,000

Sentence: In October 2009, the MoD was heavily criticized for withdrawing the bi-annual non-operational training £20m budget for the volunteer Territorial Army (TA), ending all non-operational training for 6 months until April 2010. The government eventually backed down and restored the funding. The TA provides a small percentage of the UK's operational troops. Its members train on weekly evenings and monthly weekends, as well as two-week exercises generally annually and occasionally bi-annually for troops doing other courses. The cuts would have meant a significant loss of personnel and would have had adverse effects on recruitment. 
Question: How often do the TA troops regularly train?

weekly evenings and monthly weekends
