Input: Article: The term "domestic dog" is generally used for both of the domesticated and feral varieties. The English word dog comes from Middle English dogge, from Old English docga, a "powerful dog breed". The term may possibly derive from Proto-Germanic *dukkōn, represented in Old English finger-docce ("finger-muscle"). The word also shows the familiar petname diminutive -ga also seen in frogga "frog", picga "pig", stagga "stag", wicga "beetle, worm", among others. The term dog may ultimately derive from the earliest layer of Proto-Indo-European vocabulary.

Now answer this question: What is the Proto-Germanic word that "dog" may have come from?

Output: dukkōn

Input: Article: The Arthur Ravenel Jr. Bridge across the Cooper River opened on July 16, 2005, and was the second-longest cable-stayed bridge in the Americas at the time of its construction.[citation needed] The bridge links Mount Pleasant with downtown Charleston, and has eight lanes plus a 12-foot lane shared by pedestrians and bicycles. It replaced the Grace Memorial Bridge (built in 1929) and the Silas N. Pearman Bridge (built in 1966). They were considered two of the more dangerous bridges in America and were demolished after the Ravenel Bridge opened.

Now answer this question: What year was the Silas N. Pearman Bridge built?

Output: 1966

Input: Article: Einstein partially advocates Mach's principle in that distant stars explain inertia because they provide the gravitational field against which acceleration and inertia occur. But contrary to Leibniz's account, this warped space-time is as integral a part of an object as are its other defining characteristics, such as volume and mass. If one holds, contrary to idealist beliefs, that objects exist independently of the mind, it seems that relativistics commits them to also hold that space and temporality have exactly the same type of independent existence.

Now answer this question: How does Einstein advocate Mach's principle?

Output:
partially
