Answer:
The underlined verb is in the historical present tense.
Step-by-step explanation:
The historical present is the use of the verb phrase in the present tense to refer to an event that took place in the past. It is also called the dramatic present, historic present, and narrative present. As you can see, in the sentence above the event referred to took place between the 1920s and 1930s, yet the verb is in the present tense.
