Answer:
The correct answer is: Present tense, Present Perfect, Past tense, Imperfect tense, Past Perfect.
Step-by-step explanation:
Almost all Spanish indicative tenses drop their ending from the original verb, in order to add an adequate termination for the appropriate verbal tense.
The ending forms of the verb in Spanish are: - AR, - ER, -IR
When we remove these terminations, we are able to add the terminations for a specific tense.
For example:
TRABAJ-AR
TRABAJ- O /-AS/-A
-AMOS/ÁIS/AN
The only exceptions are Future Simple and Conditional tense, where we should add the adequate termination on the infinite, instead of dropping the ending form.
For example:
VIAJAR
VIAJAR -É/-ÁS/-Á
VIAJAR /-EMOS/-EIS/-ÁN
