Article: The Battle of Spicheren, on 5 August, was the second of three critical French defeats. Moltke had originally planned to keep Bazaine's army on the Saar River until he could attack it with the 2nd Army in front and the 1st Army on its left flank, while the 3rd Army closed towards the rear. The aging General von Steinmetz made an overzealous, unplanned move, leading the 1st Army south from his position on the Moselle. He moved straight toward the town of Spicheren, cutting off Prince Frederick Charles from his forward cavalry units in the process.

Question: Which town was the site of General von Steinmetz's grave error?
Ans: Spicheren

Here is a question about this article: Over the course of thousands of years, American indigenous peoples domesticated, bred and cultivated a large array of plant species. These species now constitute 5060% of all crops in cultivation worldwide. In certain cases, the indigenous peoples developed entirely new species and strains through artificial selection, as was the case in the domestication and breeding of maize from wild teosinte grasses in the valleys of southern Mexico. Numerous such agricultural products retain their native names in the English and Spanish lexicons.
What is the answer to this question: What products sometimes retain their native names in both English and Spanish?
****
So... agricultural

Sometimes overlooked during his life, James Lind, a physician in the British navy, performed the first scientific nutrition experiment in 1747. Lind discovered that lime juice saved sailors that had been at sea for years from scurvy, a deadly and painful bleeding disorder. Between 1500 and 1800, an estimated two million sailors had died of scurvy. The discovery was ignored for forty years, after which British sailors became known as "limeys." The essential vitamin C within citrus fruits would not be identified by scientists until 1932.
The juice of which fruit was determined to have helped sailors from contracting scurvy?
****
The answer: lime

Problem: Please answer a question about the following article about Nintendo Entertainment System:
Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.
Companies did what in an effort to circumvent Nintendo's console authentication?
A: voltage spike to temporarily disable the 10NES chip

The succeeding Prussian reforms instigated by Heinrich Friedrich Karl vom und zum Stein and Karl August von Hardenberg included the implementation of an Oberlandesgericht appellation court at Konigsberg, a municipal corporation, economic freedom as well as emancipation of the serfs and Jews. In the course of the Prussian restoration by the 1815 Congress of Vienna, the East Prussian territories were re-arranged in the Regierungsbezirke of Gumbinnen and Konigsberg. From 1905, the southern districts of East Prussia formed the separate Regierungsbezirk of Allenstein. East and West Prussia were first united in personal union in 1824, and then merged in a real union in 1829 to form the Province of Prussia. The united province was again split into separate East and West Prussian provinces in 1878.

In what year was East and West Prussia first united?

Everything in between the far south and the far north is savannah (insignificant tree cover, with grasses and flowers located between trees). Rainfall is more limited, to between 500 and 1,500 millimetres (20 and 60 in) per year. The savannah zone's three categories are Guinean forest-savanna mosaic, Sudan savannah, and Sahel savannah. Guinean forest-savanna mosaic is plains of tall grass interrupted by trees. Sudan savannah is similar but with shorter grasses and shorter trees. Sahel savannah consists of patches of grass and sand, found in the northeast. In the Sahel region, rain is less than 500 millimetres (20 in) per year and the Sahara Desert is encroaching. In the dry north-east corner of the country lies Lake Chad, which Nigeria shares with Niger, Chad and Cameroon.
Which desert is encroaching into northeastern Nigeria?
Sahara
