"At" is for locations/places, not for being on top of furniture.2She lives London.Correct answer: in▸ Why?"In London" — "in" is used with cities, towns, countries, and enclosed spaces. "At London" would be wrong for a place of residence. "On London" is grammatically incorrect.3He works the airport as a security officer.Correct answer: at▸ Why?"At" = a specific location or point (at the airport, at the station, at the office).

"In the third floor" and "at the third floor" are incorrect.11Please put the books the shelf.Correct answer: on▸ Why?"On the shelf" = on the surface/ledge of the shelf.

Books rest on shelves; you put them on, not in.12She is standing the bus stop.Correct answer: at▸ Why?"At the bus stop" — specific waiting point. "At" is used with stops, stations, and waiting points. "On the bus stop" would mean on top of the post/structure.

"On a box" = on top of it; "at a box" is not a normal usage; "under a box" = beneath it.14There is a café the cinema and the bookshop.Correct answer: between▸ Why?"Between the cinema and the bookshop" — "between" is used when something is in the space separating two specific, named things.
