QUES: Private CBC affiliates are not as common as they were in the past, as many such stations have been purchased either by the CBC itself or by Canwest Global or CHUM Limited, respectively becoming E! or A-Channel (later A, now CTV Two) stations. One private CBC affiliate, CHBC-TV in Kelowna, joined E! (then known as CH) on February 27, 2006. When a private CBC affiliate reaffiliates with another network, the CBC has normally added a retransmitter of its nearest O&O station to ensure that CBC service is continued. However, due to an agreement between CHBC and CFJC-TV in Kamloops, CFJC also disaffiliated from the CBC on February 27, 2006, but no retransmitters were installed in the licence area. Former private CBC affiliates CKPG-TV Prince George and CHAT-TV Medicine Hat disaffiliated on August 31, 2008 and joined E!, but the CBC announced it will not add new retransmitters to these areas. Incidentally, CFJC, CKPG and CHAT are all owned by an independent media company, Jim Pattison Group. With the closure of E! and other changes in the media landscape, several former CBC affiliates have since joined City or Global, or closed altogether.

Which affiliate left CBC due to an agreement with CHBC?
What is the answer?
ANS: CFJC-TV in Kamloops

After repeated efforts by the Samoan independence movement, the New Zealand Western Samoa Act 1961 of 24 November 1961 granted Samoa independence effective 1 January 1962, upon which the Trusteeship Agreement terminated.

While independence was achieved at the beginning of January, Samoa annually celebrates 1 June as its independence day.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What act gave Samoa independence?
Ah, so.. New Zealand Western Samoa Act 1961


Question: The island of Guam is 30 miles (50 km) long and 4 to 12 miles (6 to 19 km) wide, 3⁄4 the size of Singapore. The island experiences occasional earthquakes due to its location on the western edge of the Pacific Plate and near the Philippine Sea Plate. In recent years, earthquakes with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike the Anatahan volcano in the Northern Mariana Islands, Guam is not volcanically active. However, due to its proximity to Anatahan, vog (i.e. volcanic smog) does occasionally affect Guam.
Try to answer this question if possible: On what island is Anatahan located?
Answer: unanswerable


QUES: The conventional merit-system degree is currently not as common in open education as it is in campus universities, although some open universities do already offer conventional degrees such as the Open University in the United Kingdom. Presently, many of the major open education sources offer their own form of certificate. Due to the popularity of open education, these new kind of academic certificates are gaining more respect and equal "academic value" to traditional degrees. Many open universities are working to have the ability to offer students standardized testing and traditional degrees and credentials. A culture is beginning to form around distance learning for people who are looking to social connections enjoyed on traditional campuses. For example, students may create study groups, meetups and movements such as UnCollege.
 What do open education sources never offer?

unanswerable
