33. This mode of transportation invented in the 1800s was made possible by the distilled petroleum called gasoline? (Which of these means of transportation typically relies on gasoline) • Automobile • Velocipede • Steamship • Railroad

Automobile

Explanation:

In simple words, In 1876, Germany produced the very first gasoline-fueled four-stroke cycle generator. Carl Brass began mass manufacture of internal burning engines for automobiles in 1886. Automobiles had entered their current stage of production by the 1890s. A road vehicle was powered by steam very early as 1769.

Thus, the correct option is A.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
