Input: Read this: The noise-based speed is defined as the exposure that will lead to a given signal-to-noise ratio on individual pixels. Two ratios are used, the 40:1 ("excellent image quality") and the 10:1 ("acceptable image quality") ratio. These ratios have been subjectively determined based on a resolution of 70 pixels per cm (178 DPI) when viewed at 25 cm (9.8 inch) distance. The signal-to-noise ratio is defined as the standard deviation of a weighted average of the luminance and color of individual pixels. The noise-based speed is mostly determined by the properties of the sensor and somewhat affected by the noise in the electronic gain and AD converter.
Question: Which ratio was subjectively determined?

Output: unanswerable


Input: Read this: The Early Cretaceous spans from 145 million to 100 million years ago. The Early Cretaceous saw the expansion of seaways, and as a result, the decline and extinction of sauropods (except in South America). Many coastal shallows were created, and that caused Ichthyosaurs to die out. Mosasaurs evolved to replace them as head of the seas. Some island-hopping dinosaurs, like Eustreptospondylus, evolved to cope with the coastal shallows and small islands of ancient Europe. Other dinosaurs rose up to fill the empty space that the Jurassic-Cretaceous extinction left behind, such as Carcharodontosaurus and Spinosaurus. Of the most successful would be the Iguanodon which spread to every continent. Seasons came back into effect and the poles got seasonally colder, but dinosaurs still inhabited this area like the Leaellynasaura which inhabited the polar forests year-round, and many dinosaurs migrated there during summer like Muttaburrasaurus. Since it was too cold for crocodiles, it was the last stronghold for large amphibians, like Koolasuchus. Pterosaurs got larger as species like Tapejara and Ornithocheirus evolved.
Question: What event of the Early Cretaceous caused the proliferation of several species?

Output: unanswerable


Input: Read this: In the 19th century, a house near Ephesus in Turkey was found, based on the visions of Anne Catherine Emmerich, an Augustinian nun in Germany. It has since been visited as the House of the Virgin Mary by Roman Catholic pilgrims who consider it the place where Mary lived until her assumption. The Gospel of John states that Mary went to live with the Disciple whom Jesus loved,[Jn 19:27] identified as John the Evangelist.[citation needed] Irenaeus and Eusebius of Caesarea wrote in their histories that John later went to Ephesus, which may provide the basis for the early belief that Mary also lived in Ephesus with John.
Question: Which disciple is known as "the Disciple whom Jesus loved?"

Output: John the Evangelist


Input: Read this: Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.
Question:  Why did Mell labs create their new type of capacitor?

Output:
unanswerable
