Question: In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes yprium (metal of Cyprus), later corrupted to uprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
Is there an answer to this question: What compounds are radioactive in copper?

Answer: unanswerable

Question: In Dutch, the diminutive is not merely restricted to nouns and exist in numerals (met z'n tweetjes, "the two of us"), pronouns (onderonsje, "tete-a-tete"), verbal particles (moetje, "shotgun marriage"), and even prepositions (toetje, "dessert"). Most notable however, are the diminutive forms of adjectives and adverbs. The former take an diminutive ending and thus functions as a noun, the latter remain adverbs and have always the diminutive with the -s appended, e.g. adjective: groen ("green") noun: groentje ("rookie"); adverb: even ("just") adverb: eventjes ("just a minute").
Is there an answer to this question: When the diminutive ending "-tjes" is added to the adverb "even," as what part of speech does it function?

Answer: adverb

Question: In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.
Is there an answer to this question: In 1803, what part of England did Victoria travel to with Dutchess of Kent and Conroy?

Answer: unanswerable

Question: Originally much of the valley laid beneath the waters of Lake Texcoco, a system of interconnected salt and freshwater lakes. The Aztecs built dikes to separate the fresh water used to raise crops in chinampas and to prevent recurrent floods. These dikes were destroyed during the siege of Tenochtitlan, and during colonial times the Spanish regularly drained the lake to prevent floods. Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.
Is there an answer to this question: What made up Lake Texcoco?

Answer:
a system of interconnected salt and freshwater lakes
