The problem: Answer a question about this article:
Due to the chemical composition of the pentose residues of the bases, DNA strands have directionality. One end of a DNA polymer contains an exposed hydroxyl group on the deoxyribose; this is known as the 3' end of the molecule. The other end contains an exposed phosphate group; this is the 5' end. The two strands of a double-helix run in opposite directions. Nucleic acid synthesis, including DNA replication and transcription occurs in the 5'→3' direction, because new nucleotides are added via a dehydration reaction that uses the exposed 3' hydroxyl as a nucleophile.:27.2
What causes the directionality of DNA strands?
****
The answer: the chemical composition of the pentose residues of the bases


The problem: Answer a question about this article:
Dutch is written using the Latin script. Dutch uses one additional character beyond the standard alphabet, the digraph IJ. It has a relatively high proportion of doubled letters, both vowels and consonants, due to the formation of compound words and also to the spelling devices for distinguishing the many vowel sounds in the Dutch language. An example of five consecutive doubled letters is the word voorraaddoos (food storage container). The diaeresis (Dutch: trema) is used to mark vowels that are pronounced separately when involving a pre- or suffix. Whereas a hyphen is used when this problem occurs in compound words. For example; "beïnvloed" (influenced), but zee-eend (sea duck). Generally, other diacritical marks only occur in loanwords, though the acute accent can also be used for emphasis or to differentiate between two forms. Its most common use is to differentiate between the indefinite article 'een' (a, an) and the numeral 'één' (one).
What's the name for the additional character Dutch uses?
****
The answer: digraph


The problem: Answer a question about this article:
Like most Slavic languages, there are mostly three genders for nouns: masculine, feminine, and neuter, a distinction which is still present even in the plural (unlike Russian and, in part, the Čakavian dialect). They also have two numbers: singular and plural. However, some consider there to be three numbers (paucal or dual, too), since (still preserved in closely related Slovene) after two (dva, dvije/dve), three (tri) and four (četiri), and all numbers ending in them (e.g. twenty-two, ninety-three, one hundred four) the genitive singular is used, and after all other numbers five (pet) and up, the genitive plural is used. (The number one [jedan] is treated as an adjective.) Adjectives are placed in front of the noun they modify and must agree in both case and number with it.
What three noun genders does Serbo-Croatian have?
****
The answer: masculine, feminine, and neuter


The problem: Answer a question about this article:
In 1887, the British Empire celebrated Victoria's Golden Jubilee. Victoria marked the fiftieth anniversary of her accession on 20 June with a banquet to which 50 kings and princes were invited. The following day, she participated in a procession and attended a thanksgiving service in Westminster Abbey. By this time, Victoria was once again extremely popular. Two days later on 23 June, she engaged two Indian Muslims as waiters, one of whom was Abdul Karim. He was soon promoted to "Munshi": teaching her Hindustani, and acting as a clerk. Her family and retainers were appalled, and accused Abdul Karim of spying for the Muslim Patriotic League, and biasing the Queen against the Hindus. Equerry Frederick Ponsonby (the son of Sir Henry) discovered that the Munshi had lied about his parentage, and reported to Lord Elgin, Viceroy of India, "the Munshi occupies very much the same position as John Brown used to do." Victoria dismissed their complaints as racial prejudice. Abdul Karim remained in her service until he returned to India with a pension on her death.
What is the point of the Golden Jubilee?
****
The answer:
the fiftieth anniversary of her accession
