Q: Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina (    ) and Harminuya (in Elamite). In Greek, Αρμένιοι "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.

A: How long ago has the term 'Armenia' been used?

Q: Israel is widely believed to possess nuclear weapons as well as chemical and biological weapons of mass destruction. Israel has not signed the Treaty on the Non-Proliferation of Nuclear Weapons and maintains a policy of deliberate ambiguity toward its nuclear capabilities. The Israeli Navy's Dolphin submarines are believed to be armed with nuclear Popeye Turbo missiles, offering nuclear second strike capability. Since the Gulf War in 1991, when Israel was attacked by Iraqi Scud missiles, all homes in Israel are required to have a reinforced security room, Merkhav Mugan, impermeable to chemical and biological substances.

A: Israel is widely believed to possess what?

Q: Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 °C or 147 °F). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948. Solar energy can also be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 terajoules (400,000 kWh) in its 68 cubic metres storage tank with an annual storage efficiency of about 99%.

A:
Paraffin wax is an example of what kind of storage media?
