Question

Choose the correct answer from the options given below the sentence:
He always to prove that the earth revolves around the sun.

• A. tried
• B. tries
• C. was trying
• D. is trying

Hint:

Signal keywords like always, usually, often, everyday, daily point directly to habitual routines. Pair them with the Simple Present Tense to ensure correct sentence structure.

Answer 1

The Correct Option is B

Concept: The choice of verb tense depends on frequency modifiers and structural clues within a sentence. The adverb 'always' signifies an ongoing habit, consistent trait, or regular recurring routine. Habitual actions, timeless characteristics, or repetitive personal behaviors are structured using the Simple Present Tense ($S + V_1 / V_{s/es}$).

Step 1: Analyze the subject and the frequency modifier.
The sentence contains the adverb 'always', which means the action is a regular habit rather than a temporary single event. The subject of the sentence is the third-person singular pronoun 'He'. In the Simple Present tense, a singular subject requires a verb ending with an '-s' or '-es' suffix modifier ($V_{s/es}$).

Step 2: Evaluate the options against simple present tense rules.
Let us filter the choices based on our tense criteria:

• (A) tried: Simple Past form. This contradicts the habitual continuity implied by 'always'.

• (B) tries: Present tense third-person singular form. This fits the subject 'He' and matches the frequency modifier 'always'.

• (C) was trying: Past Continuous form. This describes a temporary background event in the past, which does not fit here.

• (D) is trying: Present Continuous form. This describes a temporary action happening right at this moment, which conflicts with the permanent habit implied by 'always'.
This leaves 'tries' as the correct grammatical fit, matching option (B).
