Final answer:
In this sentence, the blank should be filled with the word 'tampoco'. It means 'neither' or 'either' in English. The sentence will mean 'I don't like tacos either' or 'Neither do I like tacos' when 'tampoco' is added.
Step-by-step explanation:
In the sentence, the blank should be filled with the word tampoco.
The phrase 'No me gustan los tacos' means 'I don't like tacos'. When adding 'tampoco' to the sentence, it will mean 'I don't like tacos either' or 'Neither do I like tacos'.
For example, 'No me gustan los tacos. A mí tampoco' means 'I don't like tacos. Neither do I'.
