A subordinate clause is a clause that cannot stand alone as a complete sentence.
Subordinate clauses usually begin with subordinating conjunctions which link dependent clauses to independent clauses, such as for, as, since, therefore, hence, consequently, due to, though, provided that, because, unless, once, while, when, whenever, where, wherever, before, and after.
They can also begin with relative pronouns such as that, which, who, whom, whichever, whoever, whomever, and whose.
To identify a subordinate clause, there must always have a comma after it. When the main clause starts the sentence, there is no comma to separate it from the dependent clause.
Now, let's look over the sentence:
"As I was walking, I stumbled upon a beautiful seashell."
If we use this info, we can deduce that the answer is (A. As I was walking).
After returning from the past, he was left without understanding why he was not selected for the Slytherin but for the Gryffindor.
Explanation:
This question is about "Harry Potter and the cursed child", when he uses the necklace that allows time travel, to go to the past. On this trip he is faced with innumerable information that leaves him confused, mainly in relation to him and his father. When he finishes watching and returns from the past he is very thoughtful and does not understand why he was selected for the Gryffindor, since the past shows that he must have been in the Slytherin.
