Problem: United States presidential election, 2004:

On July 6, John Kerry selected John Edwards as his running mate, shortly before the 2004 Democratic National Convention in Boston, held later that month. Days before Kerry announced Edwards as his running mate, Kerry gave a short list of three candidates: Sen John Edwards, Rep Dick Gephardt, and Gov Tom Vilsack. Heading into the convention, the Kerry/Edwards ticket unveiled their new slogana promise to make America "stronger at home and more respected in the world." Kerry made his Vietnam War experience the prominent theme of the convention. In accepting the nomination, he began his speech with, "I'm John Kerry and I'm reporting for duty." He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement.

Which famous line from Kerry's speech was later featured in one of his later television ad campaigns?
---
A: "the future doesn't belong to fear, it belongs to freedom"

Problem: It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).
What releases sperm from annelids eyes?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Evidence of Han-era mechanical engineering comes largely from the choice observational writings of sometimes disinterested Confucian scholars. Professional artisan-engineers (jiang ) did not leave behind detailed records of their work. Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described. Nevertheless, some Han literary sources provide crucial information. For example, in 15 BC the philosopher Yang Xiong described the invention of the belt drive for a quilling machine, which was of great importance to early textile manufacturing. The inventions of the artisan-engineer Ding Huan () are mentioned in the Miscellaneous Notes on the Western Capital. Around 180 AD, Ding created a manually operated rotary fan used for air conditioning within palace buildings. Ding also used gimbals as pivotal supports for one of his incense burners and invented the world's first known zoetrope lamp.
Which engineer was responsible for first inventing the zoetrope lamp?
A: Ding Huan
