QUES: Temporal measurement, chronometry, takes two distinct period forms: the calendar, a mathematical tool for organizing intervals of time, and the clock, a physical mechanism that counts the passage of time. In day-to-day life, the clock is consulted for periods less than a day whereas the calendar is consulted for periods longer than a day. Increasingly, personal electronic devices display both calendars and clocks simultaneously. The number (as on a clock dial or calendar) that marks the occurrence of a specified event as to hour or date is obtained by counting from a fiducial epoch—a central reference point.

How is the number that marks the occurrence of an event obtained?
What is the answer?
ANS: by counting from a fiducial epoch—a central reference point

Ah, so.. 4H to 7H


Question: Finance proved a major problem for the Labour Party during this period; a "cash for peerages" scandal under Blair resulted in the drying up of many major sources of donations. Declining party membership, partially due to the reduction of activists' influence upon policy-making under the reforms of Neil Kinnock and Blair, also contributed to financial problems. Between January and March 2008, the Labour Party received just over £3 million in donations and were £17 million in debt; compared to the Conservatives' £6 million in donations and £12 million in debt.
Try to answer this question if possible: Why did party membership increase?
Answer: unanswerable
