Explanation:
Determiners are words that are used before a noun to provide more information about the noun. In this sentence, the determiner is used to describe the amount of patience someone has.

Options:
a) little - This determiner indicates a small amount of patience. It suggests that the person does not have much patience.
b) few - This determiner is used to describe a small number of countable nouns. However, patience is an uncountable noun, so "few" would not be appropriate in this context.

Correct Answer:
The correct answer is option 'A' - little. This is because patience is an uncountable noun and cannot be counted. Therefore, we use the determiner "little" to describe a small amount of patience.

Using "little" in this sentence suggests that the person does not have a great deal of patience. It implies that they may become impatient easily or have a limited capacity for tolerance.

Example:
- "You have little patience, so try to be more understanding and tolerant."

In this sentence, the determiner "little" is used to describe the amount of patience someone has. It suggests that the person has a small amount of patience and should work on being more patient and understanding.

To summarize, the determiner "little" is the appropriate choice in this sentence because it accurately describes the amount of patience someone has. It indicates a small amount of patience and implies that the person may become impatient easily or have a limited capacity for tolerance.
