Problem:Like most sexual species, the sex ratio in humans is approximately 1: 1. Due to higher female fetal mortality, the sex ratio at birth worldwide is commonly thought to be 107 boys to 100 girls, although this value is subject to debate in the scientific community. The sex ratio for the entire world population is 101 males to 100 females. Depending upon which definition is used, between 0.1 % and 1.7 % of live births are intersex.

Answer this question based on the passage: ratio of male and female in the world?
Solution:OK... To answer the above question, the relevant sentence is: The sex ratio for the entire world population is 101 males to 100 females.
101 males to 100 females.

Problem:Passage: Estimates for the temperature of the outer core are about 3,000 -- 4,500 K (2,730 -- 4,230 C; 4,940 -- 7,640 F) in its outer regions and 4,000 -- 8,000 K (3,730 -- 7,730 C; 6,740 -- 13,940 F) near the inner core. Evidence for a fluid outer core includes from seismology which shows that seismic shear-waves are not transmitted through the outer core Because of its high temperature, modeling work has shown that the outer core is a low viscosity fluid that convects turbulently. Eddy currents in the nickel iron fluid of the outer core are believed to influence the Earth's magnetic field. The average magnetic field strength in the Earth's outer core was measured to be 2.5 millitesla, 50 times stronger than the magnetic field at the surface. The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to the inner core. Sulfur and oxygen could be present in the outer core.

Question: Based on this passage, what is the temperature of the earth outer core in fahrenheit?
Solution:OK... The relevant information is: Estimates for the temperature of the outer core are about 3,000 -- 4,500 K (2,730 -- 4,230 C; 4,940 -- 7,640 F) in its outer regions and 4,000 -- 8,000 K (3,730 -- 7,730 C; 6,740 -- 13,940 F) near the inner core.
3,000 -- 4,500 K ( 2,730 -- 4,230 C ; 4,940 -- 7,640 F ) in its outer regions and 4,000 -- 8,000 K ( 3,730 -- 7,730 C ; 6,740 -- 13,940 F ) near the inner core.

Student A:Passage: The Dionne quintuplets (French pronunciation: ( dzjn); born May 28, 1934 ) are the first quintuplets known to have survived their infancy. The identical sisters were born in Canada, just outside Callander, Ontario, near the village of Corbeil. All five survived to adulthood.

Question: Based on this passage, why did the birth of the dionne quintuplets create such a sensation?
Student B:OK... The important part for answering this question is: The Dionne quintuplets (French pronunciation: ( dzjn); born May 28, 1934 ) are the first quintuplets known to have survived their infancy.
the first quintuplets known to have survived their infancy.
