Question

Fill in the blank with the most appropriate word-
The detective has not solved the mystery _______.
a) Still
b) Yet
c) Already
d) Therefore

Answer 1

Hint:Read the given phrase/sentence carefully. Try to make out the meaning of it and find the subject or the predicate or the main object of the sentence.

Complete answer:
In the given question, the sentence conveys that the detective hasn't solved the mystery-
We have to fill it with an adverb. There are four words given, we have to choose the most suitable one for the given blank.
Now, let us examine all the given options to find out the correct option-
Option 'a' is Still. It means up to and including the present or the time mentioned; even now, or then. For example, He still lives with his mother.
Option 'b' is Yet. It means - but at the same time; but nevertheless. For example, The path was dark, yet I slowly found my way.
Option 'c' is Already. It means before, or the time now in question. For example, Anna has suffered a great deal already.
Option 'd' is Therefore. It means - for that reason; consequently. For example, He was injured and therefore was unable to play.
As we have analyzed all the given options, we can easily figure out the correct option. Here, the correct word to be filled in is - yet. The complete sentence would be - The detective has not solved the mystery yet. Hence, option 'b' is the correct option.

Note:
All the other options are plausible distractions. Don't confuse between 'still' and 'yet'. Still generally comes before the verb, while yet is usually placed at the end of the sentence. In question, YET has a similar meaning to already (by now).
