1. In my view the internal combustion engine had the greatest impact on transportation during the second industrial revolution. It had a good perspective in future.
2. I agree with your choice "<span>medicine advanced, and the death rate fell". The factors like hygiene, good sanitation and improved medicine caused population growth between 1800 and 1900. </span> 3. This one is correct. Unions was the perfect way to improve working conditions. Workers' unions had a great influence as human labour wasn't fully replaced and it was a good idea to invest money in good working conditions. Better conditions = better work.
4. Edison's inventions changed the world. And I think that your answer is correct. As it's the most suitable answer from given above. The structure of society has changed as this invention allowed factories and other businesses work all night long. It's really huge profit.

This one is also 100% correct. "Cities grew rapidly as people moved from rural areas to work in the industry" - it was the main trend during the second industrial revolution. This process is called urbanization if I'm not mistaken.
10. In my view correct answer is this: "T<span>he desire of middle class for parks, department stores, and wider streets." Urbanization caused huge population of middle class.</span>
The right answer for the question that is being asked and shown above is that: "9.8 years." I<span>n the state of Missouri research data, 9.8 more years did non-smokers live compared to people who smoked. Smoking really kills human slowly.</span>
