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.

Nearly 47% of Tajikistan's GDP comes from immigrant remittances (mostly from Tajiks working in Russia). The current economic situation remains fragile, largely owing to corruption, uneven economic reforms, and economic mismanagement. With foreign revenue precariously dependent upon remittances from migrant workers overseas and exports of aluminium and cotton, the economy is highly vulnerable to external shocks. In FY 2000, international assistance remained an essential source of support for rehabilitation programs that reintegrated former civil war combatants into the civilian economy, which helped keep the peace. International assistance also was necessary to address the second year of severe drought that resulted in a continued shortfall of food production. On August 21, 2001, the Red Cross announced that a famine was striking Tajikistan, and called for international aid for Tajikistan and Uzbekistan, however access to food remains a problem today. In January 2012, 680,152 of the people living in Tajikistan were living with food insecurity. Out of those, 676,852 were at risk of Phase 3 (Acute Food and Livelihoods Crisis) food insecurity and 3,300 were at risk of Phase 4 (Humanitarian Emergency). Those with the highest risk of food insecurity were living in the remote Murghob District of GBAO.
In January 2002, how many people in Tajikistan were living with food insecurity?
A: unanswerable

It is commonly believed that the earlier a defect is found, the cheaper it is to fix it. The following table shows the cost of fixing the defect depending on the stage it was found. For example, if a problem in the requirements is found only post-release, then it would cost 10100 times more to fix than if it had already been found by the requirements review. With the advent of modern continuous deployment practices and cloud-based services, the cost of re-deployment and maintenance may lessen over time.
How much less would it cost to fix a problem found after the software's release?
A:
unanswerable
