Question

Fill in the blank with the most suitable option-
George is reading a Spanish newspaper. He ____ Spanish.
a) Is to know
b) Must know
c) Had to know
d) Need to know

Answer 1

Hint: Read the given sentence carefully, try to find its core meaning, its subject, predicate, or object. We have to pay attention to the verb form in this question.

Complete answer:
 The given sentence clearly conveys that George is reading a newspaper, which is Spanish. It means that he certainly knows Spanish.
Now let us examine all the options to find out the correct answer -
Option ‘a' is Is to know. It is the correct option because as George is reading a Spanish newspaper, it is understood that he knows Spanish. “Is to know” would be the most suitable option.
Option ‘b' is Must know. It cannot be the correct option because “must know” creates a doubt whether or not George knows Spanish. It does not make it clear that George knows Spanish.
Option ‘c' is Had to know. It cannot be the correct option because “had to know” is in past tense which would automatically become wrong as the sentence is in present tense.
Option ‘d' is Need to know. It cannot be the correct option because this also does not make it clear that George knows Spanish.
As we have analyzed all the given options, we can easily figure out the correct option. Hence, the option 'a' is the correct option.

Note:
 All the other options are plausible distractions. You must know the tenses, and its usage to find out the answer to this question.
