Fill in the following blanks with suitable words :
The days are ….. In winter than in summer.

Answer

To fill in the blank in the sentence "The days are ___ in winter than in summer," we need to consider the characteristics of day length during different seasons.

1. **Understanding Day Length**: The length of the day varies with the seasons. In winter, the days are typically shorter because the Earth is tilted away from the sun, resulting in less direct sunlight.

2. **Comparing Winter and Summer**: In contrast, during summer, the Earth is tilted towards the sun, which means that the sun's rays hit the Earth more directly and for a longer duration, leading to longer days.

3. **Filling in the Blank**: Given this information, we can conclude that the correct word to fill in the blank is "shorter." Therefore, the completed sentence is: "The days are shorter in winter than in summer."

### Final Answer:
The days are **shorter** in winter than in summer.
