<u>Answer:</u>
The sequence of key ideas is as follows:
- Travel by land and water were solved in the nineteenth century.
- The twentieth century will solve the problem of flight.
- Wind resistance is a concern that needs to be solved.
- Wilbur and Orville confirm the existence of tangential force.
- Wilbur estimates they will need at least an engine weighing one hundred pounds.
- He estimates the first flying machine will only reach low speeds.
<u>Explanation:</u>
Key idea 1 introduces the main idea of travel and states that land and water travel were taken care of in the nineteenth century, leaving air travel by implication, which is stated in the next idea. It is further elaborated in detail in the third point which explains the aspect of the problem that needed to be solved. The fourth idea introduces Wilbur and Orville and states their findings on the existence of tangential force, elaborating the former's estimates in the fifth and sixth key points.
