Context and question: Antimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay, lightning or cosmic rays). This is because antimatter that came to exist on Earth outside the confines of a suitable physics laboratory would almost instantly meet the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in tiny amounts, but not in enough quantity to do more than test a few of its theoretical properties.
What does antimatter annihilate?
Answer: unanswerable
Context and question: In 1824 the British government instructed the Governor of New South Wales Thomas Brisbane to occupy Norfolk Island as a place to send "the worst description of convicts". Its remoteness, previously seen as a disadvantage, was now viewed as an asset for the detention of recalcitrant male prisoners. The convicts detained have long been assumed to be a hardcore of recidivists, or 'doubly-convicted capital respites' that is, men transported to Australia who committed fresh colonial crimes for which they were sentenced to death, and were spared the gallows on condition of life at Norfolk Island. However, a recent study has demonstrated, utilising a database of 6,458 Norfolk Island convicts, that the reality was somewhat different: more than half were detained at Norfolk Island without ever receiving a colonial conviction, and only 15% had been reprieved from a death sentence. Furthermore, the overwhelming majority of convicts sent to Norfolk Island had committed non-violent property sentences, and the average length of detention was three years.
How many convicts are no longer listed in the database at Norfolk Island?
Answer: unanswerable
Context and question: The earliest known inscriptions in Sanskrit date to the first century BCE.[citation needed] They are in the Brahmi script, which was originally used for Prakrit, not Sanskrit. It has been described as a paradox that the first evidence of written Sanskrit occurs centuries later than that of the Prakrit languages which are its linguistic descendants. In northern India, there are Brahmi inscriptions dating from the third century BCE onwards, the oldest appearing on the famous Prakrit pillar inscriptions of king Ashoka. The earliest South Indian inscriptions in Tamil Brahmi, written in early Tamil, belong to the same period. When Sanskrit was written down, it was first used for texts of an administrative, literary or scientific nature. The sacred texts were preserved orally, and were set down in writing "reluctantly" (according to one commentator), and at a comparatively late date.
What king's pillar is the most recent Brahmi inscription found on?
