You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Q: The Juris Doctor degree (J.D. or JD), also known as the Doctor of Jurisprudence degree (J.D., JD, D.Jur. or DJur), is a graduate-entry professional degree in law and one of several Doctor of Law degrees. It is earned by completing law school in Australia, Canada and the United States, and some other common law countries. It has the academic standing of a professional doctorate in the United States, a master's degree in Australia, and a second-entry, baccalaureate degree in Canada, (in all three jurisdictions the same as other professional degrees such as M.D. or D.D.S., the degrees required to be a practicing physician or dentist, respectively).

A: are you a doctor if you have a jd?

Q: The EF of the left heart, known as the left ventricular ejection fraction (LVEF), is calculated by dividing the volume of blood pumped from the left ventricle per beat (stroke volume) by the volume of blood collected in the left ventricle at the end of diastolic filling (end-diastolic volume). LVEF is an indicator of the effectiveness of pumping into the systemic circulation. The EF of the right heart, or right ventricular ejection fraction (RVEF), is a measure of the efficiency of pumping into the pulmonary circulation. A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction.

A: is ejection fraction the same as stroke volume?

Q: Heteropaternal superfecundation is common in animals such as cats and dogs. Stray dogs can produce litters in which every puppy has a different sire. Though rare in humans, cases have been documented. In one study on humans, the frequency was 2.4% among dizygotic twins whose parents had been involved in paternity suits.

A:
can you have twins and have two different fathers?
