Sentence improvement — Correct the preposition with ‘‘arrive’’ in ‘‘Mr. Smith arrived at India in June last year.’’ to follow standard travel-grammar usage for countries and large places.

Given data
Mr. Smith arrived at India in June last year.

Concept/Approach
We use ‘‘arrive in’’ with large areas (countries, big cities) and ‘‘arrive at’’ with smaller points (airports, stations, buildings). Therefore, with the country name ‘‘India’’, the correct preposition is ‘‘in’’.

Option analysis
to — ‘‘arrived to’’ is incorrect.by — Indicates agency/means; wrong here.in — Correct: ‘‘arrived in India’’.No improvement — Leaves the error ‘‘at India’’.

Common pitfalls
Overgeneralizing ‘‘at’’ for all destinations; remember the size rule (in = countries/cities, at = points/addresses).
