Are both these sentence grammatically correct?

i brought the food he ate.
or
i brought the food that he ate.

can you also provide the rule or explanation ie. restrictive clause?

No 2. I brought the food that he ate.

A restrictive modifying clause (or essential clause) is an adjective clause that is essential to the meaning of a sentence because it limits the thing it refers to. The meaning of the sentence would change if the clause were deleted. Because restrictive clauses are essential, they are not set off by commas.

should you be the one doing this journal entry? it says "your special talent or skill". are you gonna lie 'bout your talent and make us fake a talent for you?

also this is a really easy journal entry, you can just think of a skill your good at and write did you work hard to become good at this skill (ex: drawing, writing, math, playing music, etc.) or does it come naturally (like a cool trick that you can do with your body). you can do all of that in 150 words. just try and think of a talent and even if your bad at this talent just say your working hard to become good at it.
