Article: On August 18, 2011, the CRTC issued a decision that allows CBC's mandatory market rebroadcasting transmitters in analogue to remain on-air until August 31, 2012. Before that deadline, CBC's licence renewal process would take place and CBC's digital transition plans would be examined as part of that process. The requirement remains for all of CBC's full-power transmitters occupying channels 52 to 69 to either relocate to channels 2 to 51 or become low-power transmitters. In some cases, CBC has opted to reduce the power of existing transmitters to low-power transmitters, which will result in signal loss for some viewers.

Question: On what day did the CRTC agree to allow CBCs broadcasting transmitters to remain active for another year?
Ans: August 18, 2011


Article: Although the format was capable of offering higher-quality video and audio than its consumer rivals, the VHS and Betamax videocassette systems, LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and video titles themselves and the inability to record TV programming. It also remained a largely obscure format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore, and Malaysia, being the prevalent rental video medium in Hong Kong during the 1990s. Its superior video and audio quality did make it a somewhat popular choice among videophiles and film enthusiasts during its lifespan.

Question: In what city was LaserDisk used as a popular rental medium in the 1990s?
Ans: Hong Kong


Article: During the process of meiotic cell division, an event called genetic recombination or crossing-over can sometimes occur, in which a length of DNA on one chromatid is swapped with a length of DNA on the corresponding sister chromatid. This has no effect if the alleles on the chromatids are the same, but results in reassortment of otherwise linked alleles if they are different.:5.5 The Mendelian principle of independent assortment asserts that each of a parent's two genes for each trait will sort independently into gametes; which allele an organism inherits for one trait is unrelated to which allele it inherits for another trait. This is in fact only true for genes that do not reside on the same chromosome, or are located very far from one another on the same chromosome. The closer two genes lie on the same chromosome, the more closely they will be associated in gametes and the more often they will appear together; genes that are very close are essentially never separated because it is extremely unlikely that a crossover point will occur between them. This is known as genetic linkage.

Question: If the alleles on the chromatids are the same, what effect arises from genetic recombination? 
Ans: no effect


Article: Small-scale "expedition tourism" has existed since 1957 and is currently subject to Antarctic Treaty and Environmental Protocol provisions, but in effect self-regulated by the International Association of Antarctica Tour Operators (IAATO). Not all vessels associated with Antarctic tourism are members of IAATO, but IAATO members account for 95% of the tourist activity. Travel is largely by small or medium ship, focusing on specific scenic locations with accessible concentrations of iconic wildlife. A total of 37,506 tourists visited during the 2006–07 Austral summer with nearly all of them coming from commercial ships. The number was predicted to increase to over 80,000 by 2010.

Question: Since what year has tourism been ongoing to Antarctica?
Ans:
1957
