input question: Extract the answer to the question from the following context. Question: What sort of carbon is the 2'-deoxyribose nucleotide subunit? Context: The vast majority of living organisms encode their genes in long strands of DNA (deoxyribonucleic acid). DNA consists of a chain made from four types of nucleotide subunits, each composed of: a five-carbon sugar (2'-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine.:2.1???

input question: Extract the answer to the question from the following context. Question: Who is the top party executive? Context: A political party is typically led by a party leader (the most powerful member and spokesperson representing the party), a party secretary (who maintains the daily work and records of party meetings), party treasurer (who is responsible for membership dues) and party chair (who forms strategies for recruiting and retaining party members, and also chairs party meetings). Most of the above positions are also members of the party executive, the leading organization which sets policy for the entire party at the national level. The structure is far more decentralized in the United States because of the separation of powers, federalism and the multiplicity of economic interests and religious sects. Even state parties are decentralized as county and other local committees are largely independent of state central committees. The national party leader in the U.S. will be the president, if the party holds that office, or a prominent member of Congress in opposition (although a big-state governor may aspire to that role). Officially, each party has a chairman for its national committee who is a prominent spokesman, organizer and fund-raiser, but without the status of prominent elected office holders.???
output answer: president

input question: Extract the answer to the question from the following context. Question: What did Daisy do that earned her the medal? Context: Medical detection dogs are capable of detecting diseases by sniffing a person directly or samples of urine or other specimens. Dogs can detect odour in one part per trillion, as their brain's olfactory cortex is (relative to total brain size) 40 times larger than humans. Dogs may have as many as 300 million odour receptors in their nose, while humans may have only 5 million. Each dog is trained specifically for the detection of single disease from the blood glucose level indicative to diabetes to cancer. To train a cancer dog requires 6 months. A Labrador Retriever called Daisy has detected 551 cancer patients with an accuracy of 93 percent and received the Blue Cross (for pets) Medal for her life-saving skills.???
output answer: detected 551 cancer patients

input question: Extract the answer to the question from the following context. Question: What happened because antibiotics were so simple to obtain and worked so well? Context: Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. Their effectiveness and easy access led to overuse, especially in livestock raising, prompting bacteria to develop resistance. This has led to widespread problems with antimicrobial and antibiotic resistance, so much as to prompt the World Health Organization to classify antimicrobial resistance as a "serious threat [that] is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country".???
output answer:
overuse
