Input: Article: Iranian scientists outside Iran have also made some major contributions to science. In 1960, Ali Javan co-invented the first gas laser, and fuzzy set theory was introduced by Lotfi Zadeh. Iranian cardiologist, Tofy Mussivand invented and developed the first artificial cardiac pump, the precursor of the artificial heart. Furthering research and treatment of diabetes, HbA1c was discovered by Samuel Rahbar. Iranian physics is especially strong in string theory, with many papers being published in Iran. Iranian-American string theorist Kamran Vafa proposed the Vafa-Witten theorem together with Edward Witten. In August 2014, Maryam Mirzakhani became the first-ever woman, as well as the first-ever Iranian, to receive the Fields Medal, the highest prize in mathematics.

Now answer this question: Which Iranian scientist discovered HbA1c to further treatment and research of diabetes?

Output: Samuel Rahbar

Input: Article: Longstanding political tensions from the 27 year rule of William Tubman resulted in a military coup in 1980 that overthrew the leadership soon after his death, marking the beginning of political instability. Five years of military rule by the People's Redemption Council and five years of civilian rule by the National Democratic Party of Liberia were followed by the First and Second Liberian Civil Wars. These resulted in the deaths and displacement of more than half a million people and devastated Liberia's economy. A peace agreement in 2003 led to democratic elections in 2005. Recovery proceeds but about 85% of the population live below the international poverty line.

Now answer this question: How long did william tubman rule?

Output: 27 year

Input: Article: It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.

Now answer this question: What is an example of an organism which does not contain any repetitive DNA?

Output:
E. coli
