Problem: Eritrea:

Disagreements following the war have resulted in stalemate punctuated by periods of elevated tension and renewed threats of war. The stalemate led the President of Eritrea to urge the UN to take action on Ethiopia with the Eleven Letters penned by the President to the United Nations Security Council. The situation has been further escalated by the continued efforts of the Eritrean and Ethiopian leaders in supporting opposition in one another's countries.[citation needed] In 2011, Ethiopia accused Eritrea of planting bombs at an African Union summit in Addis Ababa, which was later supported by a UN report. Eritrea denied the claims.

What did Eritrea do when it was accused of planting bombs at the African Union summit?
---
A: denied the claims

Problem: Beer:

The earliest known chemical evidence of barley beer dates to circa 35003100 BC from the site of Godin Tepe in the Zagros Mountains of western Iran. Some of the earliest Sumerian writings contain references to beer; examples include a prayer to the goddess Ninkasi, known as "The Hymn to Ninkasi", which served as both a prayer as well as a method of remembering the recipe for beer in a culture with few literate people, and the ancient advice (Fill your belly. Day and night make merry) to Gilgamesh, recorded in the Epic of Gilgamesh, by the ale-wife Siduri may, at least in part, have referred to the consumption of beer. The Ebla tablets, discovered in 1974 in Ebla, Syria, show that beer was produced in the city in 2500 BC. A fermented beverage using rice and fruit was made in China around 7000 BC. Unlike sake, mould was not used to saccharify the rice (amylolytic fermentation); the rice was probably prepared for fermentation by mastication or malting.

In what country was the earliest chemical evidence of barley beer found?

A: Iran

Problem: Greeks:

Homer refers to the "Hellenes" (/hlinz/) as a relatively small tribe settled in Thessalic Phthia, with its warriors under the command of Achilleus. The Parian Chronicle says that Phthia was the homeland of the Hellenes and that this name was given to those previously called Greeks (). In Greek mythology, Hellen, the patriarch of Hellenes, was son of Pyrrha and Deucalion, who ruled around Phthia, the only survivors after the great deluge. It seems that the myth was invented when the Greek tribes started to separate from each other in certain areas of Greece and it indicates their common origin. Aristotle names ancient Hellas as an area in Epirus between Dodona and the Achelous river, the location of the great deluge of Deucalion, a land occupied by the Selloi and the "Greeks" who later came to be known as "Hellenes". Selloi were the priests of Dodonian Zeus and the word probably means "sacrificers" (compare Gothic saljan, "present, sacrifice"). There is currently no satisfactory etymology of the name Hellenes. Some scholars assert that the name Selloi changed to Sellanes and then to Hellanes-Hellenes. However this etymology connects the name Hellenes with the Dorians who occupied Epirus and the relation with the name Greeks given by the Romans becomes uncertain. The name Hellenes seems to be older and it was probably used by the Greeks with the establishment of the Great Amphictyonic League. This was an ancient association of Greek tribes with twelve founders which was organized to protect the great temples of Apollo in Delphi (Phocis) and of Demeter near Thermopylae (Locris). According to the legend it was founded after the Trojan War by the eponymous Amphictyon, brother of Hellen.

Is the name more ancient than other group names in the area ?
