Fill in the blank with the appropriate word from the options given:
As an employee working for a long time, you know too _________ who could have spilled the beans.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → well
Know (only) too well means to know something very well, often from one's own experience. An employee who has worked there for a long time knows the people very well, so he can guess who revealed the secret ("spilled the beans").
Example: I know too well how hard it is to find a job.
Complete sentence: As an employee working for a long time, you know too well who could have spilled the beans.
Why the Other Options are Incorrect?
Option 1: more — Incorrect. More is used to compare ("know more than"); "too more" is not English.
Example: She knows more about computers than I do.
Option 2: little — Incorrect. "Know too little" means to know hardly anything; a long-serving employee would know a lot, so the meaning goes against the sentence.
Example: He knows very little about cooking.
Option 3: few — Incorrect. Few is used with plural countable nouns (few people, few books); it cannot follow "know too".
Example: Few students were absent today.
