In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Which ship is older, the America, or the Enterprise?, Context: 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.
[EX A]: Enterprise

[EX Q]: Why do birds possess gizzards?, Context: Like the reptiles, birds are primarily uricotelic, that is, their kidneys extract nitrogenous waste from their bloodstream and excrete it as uric acid instead of urea or ammonia through the ureters into the intestine. Birds do not have a urinary bladder or external urethral opening and (with exception of the ostrich) uric acid is excreted along with feces as a semisolid waste. However, birds such as hummingbirds can be facultatively ammonotelic, excreting most of the nitrogenous wastes as ammonia. They also excrete creatine, rather than creatinine like mammals. This material, as well as the output of the intestines, emerges from the bird's cloaca. The cloaca is a multi-purpose opening: waste is expelled through it, most birds mate by joining cloaca, and females lay eggs from it. In addition, many species of birds regurgitate pellets. Males within Palaeognathae (with the exception of the kiwis), the Anseriformes (with the exception of screamers), and in rudimentary forms in Galliformes (but fully developed in Cracidae) possess a penis, which is never present in Neoaves. The length is thought to be related to sperm competition. When not copulating, it is hidden within the proctodeum compartment within the cloaca, just inside the vent. The digestive system of birds is unique, with a crop for storage and a gizzard that contains swallowed stones for grinding food to compensate for the lack of teeth. Most birds are highly adapted for rapid digestion to aid with flight. Some migratory birds have adapted to use protein from many parts of their bodies, including protein from the intestines, as additional energy during migration.
[EX A]: contains swallowed stones for grinding food to compensate for the lack of teeth

[EX Q]: What working group is responsible for the Universal Character Set?, Context: All Latin characters required by Pe̍h-ōe-jī can be represented using Unicode (or the corresponding ISO/IEC 10646: Universal Character Set), using precomposed or combining (diacritics) characters. Prior to June 2004, the vowel akin to but more open than o, written with a dot above right, was not encoded. The usual workaround was to use the (stand-alone; spacing) character Interpunct (U+00B7, ·) or less commonly the combining character dot above (U+0307). As these are far from ideal, since 1997 proposals have been submitted to the ISO/IEC working group in charge of ISO/IEC 10646—namely, ISO/IEC JTC1/SC2/WG2—to encode a new combining character dot above right. This is now officially assigned to U+0358 (see documents N1593, N2507, N2628, N2699, and N2713). Font support is expected to follow.
