The shirt that Jack stole was worth just three dollars, so he was only charged with a _________.

misdemeanor?

To fill in the blank in the sentence, we need to find a word that corresponds to a minor offense or misdemeanor for stealing a low-value item.

One way to find the answer is to understand the types of offenses and charges in the legal system. In this specific case, since the stolen shirt was worth only three dollars, it suggests that the offense is not severe.

A common term used for a minor theft or stealing offense is "petty theft." Petty theft typically refers to the theft of low-value items that do not exceed a specific monetary threshold (which can vary depending on jurisdiction). Therefore, the missing word in the sentence would be "petty theft."

By understanding the concept of different types of theft charges and their corresponding definitions, we can determine that Jack was only charged with "petty theft" for stealing the three-dollar shirt.
