QUES: The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.

How much was 1 troy ounce of silver worth?

QUES: At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium. A trace amount of methane is also present. Prominent absorption bands of methane exist at wavelengths above 600 nm, in the red and infrared portion of the spectrum. As with Uranus, this absorption of red light by the atmospheric methane is part of what gives Neptune its blue hue, although Neptune's vivid azure differs from Uranus's milder cyan. Because Neptune's atmospheric methane content is similar to that of Uranus, some unknown atmospheric constituent is thought to contribute to Neptune's colour.
What planet doesn't get it's color from atmospheric constituent?

Windows 8 also incorporates improved support for mobile broadband; the operating system can now detect the insertion of a SIM card and automatically configure connection settings (including APNs and carrier branding), and reduce its internet usage in order to conserve bandwidth on metered networks. Windows 8 also adds an integrated airplane mode setting to globally disable all wireless connectivity as well. Carriers can also offer account management systems through Windows Store apps, which can be automatically installed as a part of the connection process and offer usage statistics on their respective tile.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where can't Carrier account management systems be found?
Ah, so.. unanswerable

Input: Read this: Most CBC television stations, including those in the major cities, are owned and operated by the CBC itself. CBC O&O stations operate as a mostly seamless national service with few deviations from the main network schedule, although there are some regional differences from time to time. For on-air identification, most CBC stations use the CBC brand rather than their call letters, not identifying themselves specifically until sign-on or sign-off (though some, like Toronto's CBLT, do not ID themselves at all except through PSIP). All CBC O&O stations have a standard call letter naming convention, in that the first two letters are "CB" (an ITU prefix allocated not to Canada, but to Chile) and the last letter is "T". Only the third letter varies from market to market; however, that letter is typically the same as the third letter of the CBC Radio One and CBC Radio 2 stations in the same market. An exception to this rule are the CBC North stations in Yellowknife, Whitehorse and Iqaluit, whose call signs begin with "CF" due to their historic association with the CBC's Frontier Coverage Package prior to the advent of microwave and satellite broadcasting.
Question: What station does not identify itself by its call letters?

Output:
Toronto's CBLT
