Problem: Anti-aircraft warfare:

Until this time the British, at RAF insistence, continued their World War I use of machine guns, and introduced twin MG mountings for AAAD. The army was forbidden from considering anything larger than .50-inch. However, in 1935 their trials showed that the minimum effective round was an impact fused 2 lb HE shell. The following year they decided to adopt the Bofors 40 mm and a twin barrel Vickers 2-pdr (40 mm) on a modified naval mount. The air-cooled Bofors was vastly superior for land use, being much lighter than the water-cooled pom-pom, and UK production of the Bofors 40 mm was licensed. The Predictor AA No 3, as the Kerrison Predictor was officially known, was introduced with it.

What was lighter than the water-cooled pom-pom?

A: The air-cooled Bofors


Problem: Greeks:

In the Hesiodic Catalogue of Women, Graecus is presented as the son of Zeus and Pandora II, sister of Hellen the patriarch of Hellenes. Hellen was the son of Deucalion who ruled around Phthia in central Greece. The Parian Chronicle mentions that when Deucalion became king of Phthia, the previously called Graikoi were named Hellenes. Aristotle notes that the Hellenes were related with Grai/Greeks (Meteorologica I.xiv) a native name of a Dorian tribe in Epirus which was used by the Illyrians. He also claims that the great deluge must have occurred in the region around Dodona, where the Selloi dwelt. However, according to the Greek tradition it is more possible that the homeland of the Greeks was originally in central Greece. A modern theory derives the name Greek (Latin Graeci) from Graikos, "inhabitant of Graia/Graea," a town on the coast of Boeotia. Greek colonists from Graia helped to found Cumae (900 BC) in Italy, where they were called Graeces. When the Romans encountered them they used this name for the colonists and then for all Greeks (Graeci.) The word γραῖα graia "old woman" comes from the PIE root *ǵerh2-/*ǵreh2-, "to grow old" via Proto-Greek *gera-/grau-iu; the same root later gave γέρας geras (/keras/), "gift of honour" in Mycenean Greek. The Germanic languages borrowed the word Greeks with an initial "k" sound which probably was their initial sound closest to the Latin "g" at the time (Goth. Kreks). The area out of ancient Attica including Boeotia was called Graïke and is connected with the older deluge of Ogyges, the mythological ruler of Boeotia. The region was originally occupied by the Minyans who were autochthonous or Proto-Greek speaking people. In ancient Greek the name Ogygios came to mean "from earliest days".

What  is the origins of the term "old woman " ?

Problem: Zhejiang:

The area of modern Zhejiang was outside the major sphere of influence of the Shang civilization during the second millennium BC. Instead, this area was populated by peoples collectively known as the Hundred Yue, including the Dongyue and the Ouyue. The kingdom of Yue began to appear in the chronicles and records written during the Spring and Autumn Period. According to the chronicles, the kingdom of Yue was located in northern Zhejiang. Shiji claims that its leaders were descended from the Shang founder Yu the Great. Evidence suggests that Baiyue and the kingdom of Yue possessed their own culture and history that are different from those kingdoms in north and central China, whose cultures and histories were carefully recorded in chronicles and histories during the Spring and Autumn Period and into the Qin dynasty. The Song of the Yue Boatman (Chinese: 越人歌, p Yuèrén Gē, lit. "Song of the man of Yue") was transliterated into Chinese and recorded by authors in north China or inland China of Hebei and Henan around 528 BC. The song shows that the Yue people spoke a language that was mutually unintelligible with the dialects spoken in north and inland China. The Yue peoples seem to have had their own written script. The Sword of Goujian bears bird-worm seal script. Yuenü (Chinese: 越女; pinyin: Yuènǚ; Wade–Giles: Yüeh-nü; literally: "the Lady of Yue") was a swordswoman from the state of Yue. In order to check the growth of the kingdom of Wu, Chu pursued a policy of strengthening Yue. Under King Goujian, Yue recovered from its early reverses and fully annexed the lands of its rival in 473 BC. The Yue kings then moved their capital center from their original home around Mount Kuaiji in present-day Shaoxing to the former Wu capital at present-day Suzhou. With no southern power to turn against Yue, Chu opposed it directly and, in 333 BC, succeeded in destroying it. Yue's former lands were annexed by the Qin Empire in 222 BC and organized into a commandery named for Kuaiji in Zhejiang but initially headquartered in Wu in Jiangsu.

Problem: Saint Barth%C3%A9lemy:

As the terrain is generally arid, the hills have mostly poor soil and support only cacti and succulent plants. During the rainy season the area turns green with vegetation and grass. The eastern part of the island is greener as it receives more rainfall. A 1994 survey has revealed several hundred indigenous species of plants including the naturalized varieties of flora; some growing in irrigated areas while the dry areas are dominated by the cacti variety. Sea grapes and palm trees are a common sight with mangroves and shrubs surviving in the saline coastal swamps. Coconut palm was brought to the island from the Pacific islands. Important plants noted on the island are:
