Question: Passage: When granting assent by commission, the sovereign authorises three or more (normally five) lords who are Privy Counsellors to grant assent in his or her name. The Lords Commissioners, as the monarch's representatives are known, wear scarlet parliamentary robes and sit on a bench between the throne and the Woolsack. The Lords Reading Clerk reads the commission aloud; the senior commissioner then states, "My Lords, in obedience to Her Majesty's Commands, and by virtue of the Commission which has been now read, We do declare and notify to you, the Lords Spiritual and Temporal and Commons in Parliament assembled, that Her Majesty has given Her Royal Assent to the several Acts in the Commission mentioned."

Answer: Who reads the commission silently?

Question: Passage: Literature allows readers to access intimate emotional aspects of a person's character that would not be obvious otherwise. It benefits the psychological development and understanding of the reader. For example, it allows a person to access emotional states from which the person has distanced himself or herself. An entry written by D. Mitchell featured in ''The English Journal'' explains how the author utilized young adult literature in order to re-experience the emotional psychology she experienced as a child which she describes as a state of "wonder".

Answer: What gives readers access to physical aspects of a character?

Question: Passage: In England, Presbyterianism was established in secret in 1592. Thomas Cartwright is thought to be the first Presbyterian in England. Cartwright's controversial lectures at Cambridge University condemning the episcopal hierarchy of the Elizabethan Church led to his deprivation of his post by Archbishop John Whitgift and his emigration abroad. Between 1645 and 1648, a series of ordinances of the Long Parliament established Presbyterianism as the polity of the Church of England. Presbyterian government was established in London and Lancashire and in a few other places in England, although Presbyterian hostility to the execution of Charles I and the establishment of the republican Commonwealth of England meant that Parliament never enforced the Presbyterian system in England. The re-establishment of the monarchy in 1660 brought the return of Episcopal church government in England (and in Scotland for a short time); but the Presbyterian church in England continued in Non-Conformity, outside of the established church. In 1719 a major split, the Salter's Hall controversy, occurred; with the majority siding with nontrinitarian views. Thomas Bradbury published several sermons bearing on the controversy, and in 1719, "An answer to the reproaches cast on the dissenting ministers who subscribed their belief of the Eternal Trinity.". By the 18th century many English Presbyterian congregations had become Unitarian in doctrine.

Answer:
In which year was the Church of England established in secret?
