Article:  Sugar taken orally reduces the total crying time but not the duration of the first cry in newborns undergoing a painful procedure (a single lancing of the heel). It does not moderate the effect of pain on heart rate and a recent single study found that sugar did not significantly affect pain-related electrical activity in the brains of newborns one second after the heel lance procedure. Sweet oral liquid moderately reduces the incidence and duration of crying caused by immunization injection in children between one and twelve months of age.

Question: What doesn't sugar change the effect of pain on?
Ans: heart rate


Article: Karl Popper was born in Vienna (then in Austria-Hungary) in 1902, to upper middle-class parents. All of Karl Popper's grandparents were Jewish, but the Popper family converted to Lutheranism before Karl was born, and so he received Lutheran baptism. They understood this as part of their cultural assimilation, not as an expression of devout belief. Karl's father Simon Siegmund Carl Popper was a lawyer from Bohemia and a doctor of law at the Vienna University, and mother Jenny Schiff was of Silesian and Hungarian descent. After establishing themselves in Vienna, the Poppers made a rapid social climb in Viennese society: Simon Siegmund Carl became a partner in the law firm of Vienna's liberal Burgomaster Herr Grübl and, after Grübl's death in 1898, Simon took over the business. (Malachi Hacohen records that Herr Grübl's first name was Raimund, after which Karl received his middle name. Popper himself, in his autobiography, erroneously recalls that Herr Grübl's first name was Carl.) His father was a bibliophile who had 12,000–14,000 volumes in his personal library. Popper inherited both the library and the disposition from him.

Question: What numerical range of volumes did Popper's father keep in his library?
Ans:
12,000–14,000
