well for me it looks like a paragraph but since you say it's a sentence it's information and it's telling real facts I guess most of informational text have sentences mostly
1.it was a bright sunny day in April,and the clocks were striking thirteen
This is the narrative hook. A narrative hook occurs at the beginning of a passage to get the reader interested in the rest of the story. In this hook, the speaker begins talking about what seems to be a wonderful great day. Then the reader is hit with the fact that the clocks are striking thirteen. This makes it very different than what the reader is used to. While many people use a 24 hour clock instead of a 12 hour clock, it is usually only in digital form. Therefore, the word striking is not used. Striking is used for a digital clock because the hands move and are said to strike numbers. It is rare to find a 24 hour analog clock in our setting.
