However, most of the major FBS teams annually schedule early season non-conference preseason home games against lesser opponents that are lower-tier FBS, Football Championship, or Division II schools, which often result in lopsided victories in favor of the FBS teams and act as exhibition games in all but name, though they additionally provide a large appearance fee and at least one guaranteed television appearance for the smaller school. These games also receive the same criticism as NFL exhibition games, but instead it is targeted to schools scheduling low-quality opponents and the simplicity for a team to run up the score against a weak opponent. However, these games are susceptible to backfiring, resulting in damage in poll position and public perception, especially if the higher ranked team loses, although the mere act of scheduling a weak opponent is harmful to a team's overall strength of schedule itself. Games an FBS team schedules against lower division opponents do not count toward the minimum seven wins required for bowl eligibility, and only one game against an FCS team can be counted. With the start of the College Football Playoff system for the 2014 season, major teams are now discouraged from scheduling weaker opponents for their non-conference schedule because of a much higher emphasis on strength of schedule than in the Bowl Championship Series era.

Ah, so.. 2014

Uranium-238 is the most stable isotope of uranium, with a half-life of about 4.468109 years, roughly the age of the Earth. Uranium-235 has a half-life of about 7.13108 years, and uranium-234 has a half-life of about 2.48105 years. For natural uranium, about 49% of its alpha rays are emitted by each of 238U atom, and also 49% by 234U (since the latter is formed from the former) and about 2.0% of them by the 235U. When the Earth was young, probably about one-fifth of its uranium was uranium-235, but the percentage of 234U was probably much lower than this.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of the alpha rays of natural uranium are emitted by 234U?
Ah, so.. 49%

The 1960s and 1970s saw an acceleration in the decolonisation of Africa and the Caribbean. Over 20 countries gained independence from Britain as part of a planned transition to self-government. In 1965, however, the Rhodesian Prime Minister, Ian Smith, in opposition to moves toward majority rule, declared unilateral independence from Britain while still expressing "loyalty and devotion" to Elizabeth. Although the Queen dismissed him in a formal declaration, and the international community applied sanctions against Rhodesia, his regime survived for over a decade. As Britain's ties to its former empire weakened, the British government sought entry to the European Community, a goal it achieved in 1973.

Ah, so..
