Discuss the significance of Mr. Douglas’s brand and the moat?

The correct answer to this open question is the following.

The significance of Mr.Douglas’s brand and the moat is that these represent a somehow kind of protection against the enemies of inspector Edwards. He needs something to defend against enemies and he uses both as a protective shield from the secret society he discovered.

This is part of the story "Valley of Fear," written by Arthur Conan Doyle, about the famous character Sherlock Holmes. Indeed, it was the final novel about the acclaimed detective Holmes.

a. "to practice" is the best phrase to complete the sentence.

explanation:

during the summer, she likes to practice her soccer skills so that she is ready to play in the fall.

(note that : all the other options "the practicing of", "practice for" and "to do a practice on" are inappropriate as they make the sentence grammatically incorrect.)

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.
