Explanation: To clarify further, this exercise requires selecting the proper form of the verbs SER and ESTAR, which both mean "TO BE" in English. Many learners of Spanish struggle to distinguish these two verbs. Generally, ESTAR is used when describing a state resulting from a change, either actual or perceived, and to indicate location. For example, in sentence 5: "He is overwhelmed (he has become that way) by his studies," which is why ESTAR is used. Conversely, SER is applied for general descriptions or to identify someone, such as in sentence 11: "Julia, you are a good girl."
