<span>1) educated people of the Middle Ages did NOT think (nor did the Church teach) that the earth was flat!! They had known otherwise for over two millennia! (Opposition to Columbus's plans was based on the belief that the world was LARGER than he thought, and the voyage too far to make safely. In fact, his CRITICS were correct about the earth's size!)

<span>The correct answer is C. the OPEC oil embargo. Basically what happened was that the United States supported Israel in a war and the Arab Petroleum Exporting Countries decided to put an embargo on oil trading which meant that there was a shortage of oil in the United States and that what little they could get would be extremely expensive.</span>
Explanation:
- Carving is the act of using tools to shape something from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and yet soft enough for portions to be scraped away with available tools.
- A microlith is a small stone tool usually made of flint or chert and typically a centimetre or so in length and half a centimetre wide. They were made by humans from around 35,000 to 3,000 years ago, across Europe, Africa, Asia and Australia. The microliths were used in spear points and arrowheads.
