Problem: Tuberculosis:

Using histological stains on expectorated samples from phlegm (also called "sputum"), scientists can identify MTB under a microscope. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus. The most common acid-fast staining techniques are the ZiehlNeelsen stain and the Kinyoun stain, which dye acid-fast bacilli a bright red that stands out against a blue background. Auramine-rhodamine staining and fluorescence microscopy are also used.

What's the term for bacillus that can be exposed to acidic solutions without losing their stains?
---
A: acid-fast

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Shang dynasty oracle bone script and the Zhou dynasty scripts found on Chinese bronze inscriptions are no longer used; the oldest script that is still in use today is the Seal Script ((), zhuanshu). It evolved organically out of the Spring and Autumn period Zhou script, and was adopted in a standardized form under the first Emperor of China, Qin Shi Huang. The seal script, as the name suggests, is now used only in artistic seals. Few people are still able to read it effortlessly today, although the art of carving a traditional seal in the script remains alive; some calligraphers also work in this style.
What script is the oldest and still in use today?
A: Seal

Context and question: Though the proportions were always important in Greek art, the appeal of the Greek sculptures eludes any explanation by proportion alone. The statues of Apollo were thought to incarnate his living presence, and these representations of illusive imaginative reality had deep roots in the Minoan period, and in the beliefs of the first Greek speaking people who entered the region during the bronze-age. Just as the Greeks saw the mountains, forests, sea and rivers as inhabited by concrete beings, so nature in all of its manifestations possesses clear form, and the form of a work of art. Spiritual life is incorporated in matter, when it is given artistic form. Just as in the arts the Greeks sought some reality behind appearances, so in mathematics they sought permanent principles which could be applied wherever the conditions were the same. Artists and sculptors tried to find this ideal order in relation with mathematics, but they believed that this ideal order revealed itself not so much to the dispassionate intellect, as to the whole sentient self. Things as we see them, and as they really are, are one, that each stresses the nature of the other in a single unity.
Representations of illusive imaginative reality had deep roots in what period?
Answer: Minoan

Question: In 2008, Dahabshiil Group acquired a majority stake in Somtel Network, a Hargeisa-based telecommunications firm specialising in high speed broadband, mobile internet, LTE services, mobile money transfer and mobile phone services. The acquisition provided Dahabshiil with the necessary platform for a subsequent expansion into mobile banking, a growth industry in the regional banking sector. In 2014, Somalia's three largest telecommunication operators, Hormuud Telecom, NationLink and Somtel, also signed an interconnection agreement. The cooperative deal will see the firms establish the Somali Telecommunication Company (STC), which will allow their mobile clients to communicate across the three networks.
Is there an answer to this question: How many networks do STC customers still not have access to?

Answer: unanswerable

Problem: Virgil:

Book 1 (at the head of the Odyssean section) opens with a storm which Juno, Aeneas' enemy throughout the poem, stirs up against the fleet. The storm drives the hero to the coast of Carthage, which historically was Rome's deadliest foe. The queen, Dido, welcomes the ancestor of the Romans, and under the influence of the gods falls deeply in love with him. At a banquet in Book 2, Aeneas tells the story of the sack of Troy, the death of his wife, and his escape, to the enthralled Carthaginians, while in Book 3 he recounts to them his wanderings over the Mediterranean in search of a suitable new home. Jupiter in Book 4 recalls the lingering Aeneas to his duty to found a new city, and he slips away from Carthage, leaving Dido to commit suicide, cursing Aeneas and calling down revenge in a symbolic anticipation of the fierce wars between Carthage and Rome. In Book 5, Aeneas' father Anchises dies and funeral games are celebrated for him. On reaching Cumae, in Italy in Book 6, Aeneas consults the Cumaean Sibyl, who conducts him through the Underworld where Aeneas meets the dead Anchises who reveals Rome's destiny to his son.

Who is Aeneas' enemy throughout the Aeneid?
---
A:
Juno
