;
The correct option to fill in the blank is consists . Therefore, the complete sentence should be: 'The United States of America consists of people of all nationalities.'
Here’s why consists is the right choice:
Subject-Verb Agreement : The subject of the sentence is 'The United States of America,' which is considered a singular entity. For singular nouns, we typically use a verb that ends with 's' in the present tense, like 'consists.'
Simple Present Tense : The sentence is presenting a general truth or fact about the United States. In such cases, the simple present tense is typically used. The verb 'consists' is in the simple present tense and fits the context appropriately.
Eliminating Other Options :
Option 1: consist - This is the base form of the verb and is suitable for plural subjects. However, since 'The United States of America' is a singular noun, this option is incorrect.
Option 2: consisting - This is the present participle form of the verb and is usually used in continuous tenses or as an adjective, neither of which suits this context.
Option 3: have consisted - This is the present perfect tense, which is not appropriate here as it indicates an action that started in the past and continues to the present or an action that occurred at an unspecified time. The sentence is addressing a general, timeless fact.
By using 'consists,' the sentence correctly conveys that the makeup of the United States includes people from all around the world.
