The boy ___________ the bird almost everyday.

Explanation: 'Almost every day' signals a habitual action → Simple Present Tense. Subject is 'the boy' (third-person singular) → add '-es': catches.

(1) 'Catch' is base form — used with I/We/You/They, not with He/She/It.

(3) 'Catching' is present participle — needs an auxiliary like 'is'.

(4) 'Caught' is past tense — inconsistent with the habitual 'every day'.
