Problem: Bacteria:

Certain genera of Gram-positive bacteria, such as Bacillus, Clostridium, Sporohalobacter, Anaerobacter, and Heliobacterium, can form highly resistant, dormant structures called endospores. In almost all cases, one endospore is formed and this is not a reproductive process, although Anaerobacter can make up to seven endospores in a single cell. Endospores have a central core of cytoplasm containing DNA and ribosomes surrounded by a cortex layer and protected by an impermeable and rigid coat. Dipicolinic acid is a chemical compound that composes 5% to 15% of the dry weight of bacterial spores. It is implicated as responsible for the heat resistance of the endospore.

Is creating endospore a reproductive process?
---
A: is not a reproductive process


Problem: Tristan da Cunha:

On 23 May 2001, the islands experienced an extratropical cyclone that generated winds up to 190 kilometres per hour (120 mph). A number of structures were severely damaged and a large number of cattle were killed, prompting emergency aid, provided by the British government.

In miles, what is the equivalent of 120 kilometres per hour?
---
A: unanswerable


Problem: Virgil:

Publius Vergilius Maro (Classical Latin: [ˈpuː.blɪ.ʊs wɛrˈɡɪ.lɪ.ʊs ˈma.roː]; October 15, 70 BC – September 21, 19 BC), usually called Virgil or Vergil /ˈvɜːrdʒᵻl/ in English, was an ancient Roman poet of the Augustan period. He is known for three major works of Latin literature, the Eclogues (or Bucolics), the Georgics, and the epic Aeneid. A number of minor poems, collected in the Appendix Vergiliana, are sometimes attributed to him.

What is Virgil's longest book?
---
A: unanswerable


Problem: Compact disc:

CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.

Where is the metal reflective layer located?

A:
