Final answer:
The phrase "blows hot and cold" refers to a person who is unpredictable or moody, not to someone in a place with changing weather conditions. The correct interpretation of this idiom is that it describes the fluctuating enthusiasm or interest of an individual.
Step-by-step explanation:
The phrase "blows hot and cold" is a metaphorical English expression that describes a person's behavior rather than the weather. It is used to indicate that someone is moody or unpredictable, showing enthusiasm or positivity at one moment and negativity or disinterest the next. The idiom does not relate to actual temperature changes in the environment but to the changeable nature of an individual’s mood or opinions.
For example, someone might say a friend blows hot and cold if that friend seems very excited about planning a trip together one day, but seems disinterested or unwilling to discuss it the next day. This behavior can be confusing and frustrating to others, as it is difficult to predict how the person will act at any given time.
The correct answer to the question is: The phrase "blows hot and cold" means that the person is unpredictable or has mood swings, rather than being in a place where the weather changes frequently. Therefore, the right choice among the given options would be 2) Unpredictable.
