I think the answer is "In 1867, the United States bought Alaska from Russia for $7 million". When you ask the question "when" the question is asking about time.  In this excerpt, when is answered by "in 1987". while the sentence supported it is the event that happened during that time, which is " The US bought Alaska from Russia for $7 million.

Hey there!
A concrete noun is something people can see, touch, or basically use sense with.
Dog - This answer should be correct because you can use your senses with a dog. You can touch a dog with your hands and use your sense of touch.
Steve - This is a proper noun because this is a name of a person.
Wall - This is a common noun because it is just a thing/object.
Monica - This will also be a proper noun because it is someone's name.
Your final answer will be option A.
"Dog" is the concrete noun.
Hope this helps you.
Have a great day!
