Question

Fill in the blank with the most appropriate word.
She showed me some pictures _____ were very interesting.

a) that
b) all
c) their
d) they

Answer 1

Hint: The words on either side of the blanks can be separate sentences that are grammatically correct. So, the given sentence requires the use of a conjunction.

Complete answer:

The given sentences can be split into two separate sentences that are complete on their own. They can be ‘She showed me some pictures’ and ‘They were very interesting’.

Usually, to join these sentences, we require the use of conjunctions. In grammar, the conjunction is a part of speech that connects words, sentences, or clauses that require connecting.
For example, ‘She was hungry. She was thirsty.’ These two sentences can be joined by using the conjunction ‘and’. Then, that would be written as ‘She was hungry and thirsty’.
It connects two sentences so that they are not too wordy.

Now, let’s have a look at our options one by one:

that - The word ‘that’ is very versatile. It can be used as a definite article, an adjective, an adverb, as well as a conjunction. This word can join the two sentences, and therefore, it is the appropriate word. So, this is the correct option.
all - The word ‘all’ is also very versatile as it can be used as an adjective, an adverb, a noun, or a pronoun. But, it is not used as a conjunction. So, this is an incorrect option.
their - The word ‘their’ is used as a plural possessive. It cannot be used as a conjunction. So, this is an incorrect option.
they - The word ‘they’ is used as a plural pronoun in the third person. It cannot be used as a conjunction to join the above sentences. So, this is an incorrect option.

Hence, the word that should be used to fill the blank is ‘that’.

Note: Go through the options one by one and pick out the appropriate conjunction.
