Problem: With the deactivation of USS Enterprise in December 2012, the U.S. fleet comprises 10 supercarriers. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or maybe eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5 billion (plus $12 billion for development and research) for the 100,000 ton Gerald R. Ford-class carrier (estimated service 2016) compared to the smaller $2 billion 45,000 ton America-class amphibious assault ships, which are able to deploy squadrons of F-35Bs. The first of this class, USS America, is now in active service with another, USS Tripoli, under construction and 9 more are planned.
How many new carriers per year did the House Armed Services Seapower subcommittee recommend in 7/24/07?
The answer is the following: one every four years

Problem: Cargo and transport aircraft are typically used to deliver troops, weapons and other military equipment by a variety of methods to any area of military operations around the world, usually outside of the commercial flight routes in uncontrolled airspace. The workhorses of the USAF Air Mobility Command are the C-130 Hercules, C-17 Globemaster III, and C-5 Galaxy. These aircraft are largely defined in terms of their range capability as strategic airlift (C-5), strategic/tactical (C-17), and tactical (C-130) airlift to reflect the needs of the land forces they most often support. The CV-22 is used by the Air Force for the U.S. Special Operations Command (USSOCOM). It conducts long-range, special operations missions, and is equipped with extra fuel tanks and terrain-following radar. Some aircraft serve specialized transportation roles such as executive/embassy support (C-12), Antarctic Support (LC-130H), and USSOCOM support (C-27J, C-145A, and C-146A). The WC-130H aircraft are former weather reconnaissance aircraft, now reverted to the transport mission.
What did the USAF use the WC-130H aircraft for before they converted them for transport missions? 
The answer is the following: weather reconnaissance aircraft

Problem: Modern examples particularly include Chinese characters for SI units. In Chinese these units are disyllabic and standardly written with two characters, as 厘米 límǐ "centimeter" (厘 centi-, 米 meter) or 千瓦 qiānwǎ "kilowatt". However, in the 19th century these were often written via compound characters, pronounced disyllabically, such as 瓩 for 千瓦 or 糎 for 厘米 – some of these characters were also used in Japan, where they were pronounced with borrowed European readings instead. These have now fallen out of general use, but are occasionally seen. Less systematic examples include 圕 túshūguǎn "library", a contraction of 圖書館, A four-morpheme word, 社会主义 shèhuì zhǔyì "socialism", is commonly written with a single character formed by combining the last character, 义, with the radical of the first, 社, yielding roughly 礻义.
What is a less systematic example?
The answer is the following: túshūguǎn

Problem: The genome size, and the number of genes it encodes varies widely between organisms. The smallest genomes occur in viruses (which can have as few as 2 protein-coding genes), and viroids (which act as a single non-coding RNA gene). Conversely, plants can have extremely large genomes, with rice containing >46,000 protein-coding genes. The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences.
Which organism acts as a single non coding RNA gene?
The answer is the following:
viroids
