Problem: Antibiotics:

Interactions between alcohol and certain antibiotics may occur and may cause side-effects and decreased effectiveness of antibiotic therapy. While moderate alcohol consumption is unlikely to interfere with many common antibiotics, there are specific types of antibiotics with which alcohol consumption may cause serious side-effects. Therefore, potential risks of side-effects and effectiveness depend on the type of antibiotic administered. Despite the lack of a categorical counterindication, the belief that alcohol and antibiotics should never be mixed is widespread.

Is it OK to drink alcohol while taking any risks?

Problem: For its 2015 season, the league consisted of 12 teams, all from the United States; however, upon the completion of the regular season, the league announced that the two teams it had assumed operation of during the season would cease all operations effective immediately; a regular season game slated between the two had previously been canceled and declared a tie. Subsequently, one of the remaining teams, the Spokane Shock, severed its ties with the league to join the competing IFL. The AFL is divided into two conferences the American Conference and National Conference. Starting 2016, each conference will have only four teams as the champion San Jose SaberCats announced in November 2015 that they were ceasing activity for "reasons not associated with League operations."
As of 2016, how many teams does each conference have?

Question: Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system.

Problem: Aircraft carrier:

One STOBAR carrier: Liaoning was originally built as the 57,000 tonne Soviet Admiral Kuznetsov-class carrier Varyag and was later purchased as a stripped hulk by China in 1998 on the pretext of use as a floating casino, then partially rebuilt and towed to China for completion. Liaoning was commissioned on 25 September 2012, and began service for testing and training. On 24 or 25 November 2012, Liaoning successfully launched and recovered several Shenyang J-15 jet fighter aircraft. She is classified as a training ship, intended to allow the navy to practice with carrier usage. On 26 December 2012, the People's Daily reported that it will take four to five years for Liaoning to reach full capacity, mainly due to training and coordination which will take significant amount of time for Chinese PLA Navy to complete as this is the first aircraft carrier in their possession. As it is a training ship, Liaoning is not assigned to any of China's operation fleets.

What isn't Liaoning classifed as?
