The five Great Lakes are located in the north-central portion of the country, four of them forming part of the border with Canada, only Lake Michigan situated entirely within United States. The southeast United States contain subtropical forests and, near the gulf coast, mangrove wetlands, especially in Florida. West of the Appalachians lies the Mississippi River basin and two large eastern tributaries, the Ohio River and the Tennessee River. The Ohio and Tennessee Valleys and the Midwest consist largely of rolling hills and productive farmland, stretching south to the Gulf Coast.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of land makes up the Ohio and Tennessee valleys?
Ah, so.. rolling hills and productive farmland

The country is a significant agricultural producer within the EU. Greece has the largest economy in the Balkans and is as an important regional investor. Greece was the largest foreign investor in Albania in 2013, the third in Bulgaria, in the top-three in Romania and Serbia and the most important trading partner and largest foreign investor in the former Yugoslav Republic of Macedonia. The Greek telecommunications company OTE has become a strong investor in former Yugoslavia and in other Balkan countries.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is Greece a significant consumer of outside the EU?
Ah, so.. unanswerable

Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually display the actual capacitance together with the unit (for example, 220 μF). Smaller capacitors like ceramics, however, use a shorthand consisting of three numeric digits and a letter, where the digits indicate the capacitance in pF (calculated as XY × 10Z for digits XYZ) and the letter indicates the tolerance (J, K or M for ±5%, ±10% and ±20% respectively).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What part of the electrical characteristics of smaller capacitors do the digits of the abbreviated notation represent ?
Ah, so..
the digits indicate the capacitance
