Concept:The speaker first mistakes the bats for swallows because of the way they fly and swoop near the water.
Explanation:In Lawrence's "Bat", the poet persona watches some creatures flying in the evening air.
Their movement is swift, dipping, and full of sudden turns.
Because this behaviour closely resembles the flight of swallows, the persona assumes they are swallows.
He even believes he can identify them by the way they skim low and seem to touch the water.
Only upon closer and more careful observation does he realise that these creatures are bats.
This discovery fills him with shock and disgust.
The word "pipistrello" in the options is itself a type of bat, so it cannot be the creature the persona first imagines.
The whole effect of the poem depends on this mistaken identity.
The title "Bat" is revealed only after the persona has been deceived by appearances.
Therefore, the persona's initial error is to call the flying creatures swallows.
Answer:A. swallows
