which of the following is not true about galileo?
*note: this question is multiple choice. there's more than one answer.*

a. he was such a brilliant mathematician that he became a professor of mathematics at the age of 25.
b. he developed a new and improved thermometer and a better compass.
c. he designed a telescope 10 times more powerful than earlier models.
d. he was able to prove that ptolemy's theory that the moon had a smooth, polished surface was true.
e. at the inquisition he signed a paper taking back his radical ideas about the earth revolving around the sun.

Letter E. When the Inquisition tried to force him to take back his beliefs of the Earth moving around the sun, there was no proof that he did. "And yet it moves" were the words that he said under his breath when with the Inquisition. So that is what makes many people believe that he did not believe in what he told them to cause them to calm their nerves.

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
