Explanation:

To solve these multiple - choice questions, we analyze each one based on the knowledge about Alfred Nobel and nitroglycerin:

Question 1

Nitroglycerin was first made by Ascanio Sobrero. Alfred Nobel is known for making it safer (by inventing dynamite), and the other options (Milton and Lester B. Pearson) are not related to the discovery of nitroglycerin.
So the answer is B.

Question 2

Alfred Nobel had to experiment on a barge in the middle of a lake because nitroglycerine explodes on land. If he experimented on land, the explosion would be very dangerous. Nitroglycerin can explode in water - related situations too, and the idea that it must be kept wet is not the reason for using a barge.
So the answer is A.

Question 3

In the context of "a barge in the middle of a lake", a barge is a boat. "To enter without permission" is "trespass", "island" is a landmass, and "dock" is a structure for boats, not the boat itself.
So the answer is C.

Question 4

Alfred Nobel's brother died in the factory in Germany. There is no information to suggest he died on the barge or in the workshop, and the option about working in the factory in Germany is not the correct description of his fate.
So the answer is D.

Question 5

Nobel made nitroglycerine less dangerous by mixing it with a special dirt (to make dynamite). Inventing the blasting cap is related to detonation, making it in Scotland and carrying it in steamships are not the ways to make it less dangerous.
So the answer is B.

Question 6

Nobel died on December 10, 1896. He was rich, and he died in San Remo, Italy (not Paris, France), and the option "all of the above" is incorrect.
So the answer is C.

Question 7

More Canadians won the Nobel Prize for medicine. While Canadians have won in other fields too, medicine has seen a relatively higher number of Canadian Nobel laureates compared to the other options in this context.
So the answer is D.
