Input: Article: Soviet Premier Nikita Khrushchev announced that a "spy-plane" had been shot down but intentionally made no reference to the pilot. As a result, the Eisenhower Administration, thinking the pilot had died in the crash, authorized the release of a cover story claiming that the plane was a "weather research aircraft" which had unintentionally strayed into Soviet airspace after the pilot had radioed "difficulties with his oxygen equipment" while flying over Turkey. The Soviets put Captain Powers on trial and displayed parts of the U-2, which had been recovered almost fully intact.

Now answer this question: What did the Eisenhower administration refer to the downed U-2 as?

Output: weather research aircraft

Input: Article: Somalis (Somali: Soomaali, Arabic: ) are an ethnic group inhabiting the Horn of Africa (Somali Peninsula). The overwhelming majority of Somalis speak the Somali language, which is part of the Cushitic branch of the Afro-Asiatic family. They are predominantly Sunni Muslim. Ethnic Somalis number around 16-20 million and are principally concentrated in Somalia (around 12.3 million), Ethiopia (4.6 million), Kenya (2.4 million), and Djibouti (464,600), with many also residing in parts of the Middle East, North America and Europe.

Now answer this question: How many people of Somali ethnicity live in Somalia?

Output: 12.3 million

Input: Article: Insect respiration is accomplished without lungs. Instead, the insect respiratory system uses a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need it via their trachea (element 8 in numbered diagram). Since oxygen is delivered directly, the circulatory system is not used to carry oxygen, and is therefore greatly reduced. The insect circulatory system has no veins or arteries, and instead consists of little more than a single, perforated dorsal tube which pulses peristaltically. Toward the thorax, the dorsal tube (element 14) divides into chambers and acts like the insect's heart. The opposite end of the dorsal tube is like the aorta of the insect circulating the hemolymph, arthropods' fluid analog of blood, inside the body cavity.:6165 Air is taken in through openings on the sides of the abdomen called spiracles.

Now answer this question: Insect's respiratory system contains sacs, and what else?

Output:
internal tubes
