Question: This is a socio-economic bloc of nations in or near the Caribbean Sea. Other outlying member states include the Co-operative Republic of Guyana and the Republic of Suriname in South America, along with Belize in Central America. The Turks and Caicos Islands, an associate member of CARICOM, and the Commonwealth of The Bahamas, a full member of CARICOM, are in the Atlantic, but near to the Caribbean. Other nearby nations or territories, such as the United States, are not members (although the US Commonwealth of Puerto Rico has observer status, and the United States Virgin Islands announced in 2007 they would seek ties with CARICOM). Bermuda, at roughly a thousand miles from the Caribbean Sea, has little trade with, and little economically in common with, the region, and joined primarily to strengthen cultural links.
Is there an answer to this question: What status do the United States Virgin Islands have with CARICOM?

Answer: unanswerable

Question: In 1952 researchers at Ciba discovered the first orally available vasodilator, hydralazine. A major shortcoming of hydralazine monotherapy was that it lost its effectiveness over time (tachyphylaxis). In the mid-1950s Karl H. Beyer, James M. Sprague, John E. Baer, and Frederick C. Novello of Merck and Co. discovered and developed chlorothiazide, which remains the most widely used antihypertensive drug today. This development was associated with a substantial decline in the mortality rate among people with hypertension. The inventors were recognized by a Public Health Lasker Award in 1975 for "the saving of untold thousands of lives and the alleviation of the suffering of millions of victims of hypertension".
Is there an answer to this question: What is Ciba used to treat?
