1. Incorrect tense: "Starts yesterday" is grammatically incorrect. "Starts" implies an ongoing action, but "yesterday" refers to a past event.
2. Unclear meaning: The sentence could be interpreted in two ways:
* You love your shop class *because* it started yesterday.
* You love your shop class, and you are referring to a past event - the class starting yesterday.
To fix the sentence, you need to clarify the meaning and use the correct tense:
Option 1 (If the class just started):
* "You love your shop class, which started yesterday."
Option 2 (If you are referring to a past event):
* "You loved your shop class, which started yesterday."
Option 3 (If you are referring to a past event and want to emphasize loving the class):
* "You still love your shop class, even though it started yesterday."
