Answer:
False.
Step-by-step explanation:
An adjective can be defined as a word used to qualify or modify a noun. Some examples of an adjective are big, fat, thin, small, happy, beautiful, strong, hot, weak, funny, sweet, bitter, cold, etc.
For example, Vice President Kamala is bold, big and beautiful.
Therefore, the phrase "in the farm" as used in the sentence "That extremely cold day killed thousands of chicken in the farm," is not an adjective.
