Question

Accepted Answer

### Question 6
# Brief Explanations:
The Bessemer process involves blowing air through molten iron to remove impurities (like carbon) efficiently, which was Henry Bessemer's technique for making high - quality steel with less effort. Option a is about stainless steel (mixing chromium and iron), option b is a general iron - making process, and option d is casting, not the Bessemer technique.
# Answer:
c. Blowing air through melted iron to remove impurities

### Question 7
# Brief Explanations:
A turnpike is a toll road, where users pay a toll to use it. Option a describes a natural road, option c is about a waterway for irrigation, and option d is about a railway track, not a turnpike.
# Answer:
b. A road that people pay a toll to use

### Question 8
# Brief Explanations:
Thomas Telford and John McAdam (Jon McAdam in the option) were known for improving road construction by creating smooth surfaces and proper drainage (McAdam's method and Telford's road - building work). The other pairs: Abraham Darby and Henry Bessemer were related to iron/steel, George Stephenson to railways, and Samuel Slater to textiles.
# Answer:
d. Thomas Telford and Jon McAdam

### Question 9
# Brief Explanations:
Canal locks are used to safely raise and lower vessels to different water levels (elevations) so that boats can navigate between sections of canals with different water heights. Option a is incorrect as locks don't connect to railroads, option b is about steam - boat speed (not related to locks), and option c is about security (not the main function of locks).
# Answer:
d. Safely raised and lowered vessels so they could change elevation

### Question 10
# Brief Explanations:
Improved transportation like railroads reduced the cost of shipping goods (faster and more efficient) and made products more available (easier to transport to more places). Option a is wrong as canals were still used, option b is wrong as factories could be located away from waterways, and option c is wrong as costs should decrease, not prices increase due to demand in this context.
# Answer:
d. Reduced cost of shipping goods and increased product availability
