D. Calbraith Perry Rodgers

Explanation:

The first crossing of the United States by airplane was achieved by Calbraith Perry Rodgers in 1911. In 1910, famed publishing magnate William Randolph Hearst announced his offer of a $50,000-prize for a U.S. transcontinental flight in thirty days or less. Rodgers' Wright EX biplane was named the Vin Fiz after his sponsor's grape soda product. He left Sheepshead Bay, New York, on September 17, 1911. A "hangar" car, a rolling workshop filled with spare parts to repair and maintain the airplane, followed along. The flight was punctuated by numerous stops, delays, and accidents. When Hearst's 30-day time limit expired, Rodgers had only reached Kansas City, Missouri. Undaunted, he continued on, determined to make the first transcontinental airplane flight whether he received the money or not. He arrived in Pasadena, California, to a hero's welcome, 49 days after setting out. Although Pasadena was the official end of the coast-to-coast journey, Rodgers flew on to Long Beach to complete the flight at the shore of the Pacific Ocean. The total distance covered was 6,914 km (4,321 mi) in 82 hours, 4 minutes, total flying time at an average speed of 82.4 kph (51.5 mph).

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !

the invasive species was introduced due to commercial purpouses, as there was a demand for fur clothes and hence, a business opportunity connected to this product. actually, it was when the nutrias scaped, causing harm to the us ecosystems when they acquired the status of invasive species. in this case they have caused an environmental problem, but it could have affected also economic interests or even human health.
