Answer and Explanation:
There is the same error repeated in two places in this sentence. This is because the sentence needs conjunctions before the verb "to fly" and before the word "lucy". Conjunctions are words that allow connections between the clauses of a sentence, allowing them to be read with fluidity and cohesion. Without these conjunctions, sentences are incorrect and incoherent.
The sentence written with the conjunctions correctly would be:
"Learning how to fly a plane and swimming were two skills that Lucy really wanted to learn."
