Statement I Despite the northerly latitude, the climate of U.K. is generally mild. Statement II Warm air from North Atlantic Drift and Western Africa combines with cold wet air from the Arctic and Iceland.

Statement I is true as the United Kingdom experiences a mild maritime climate despite its high northerly latitude, which would otherwise result in severe winters similar to Labrador [c1, t2]. Statement II is also true and provides the correct explanation. The UK's climate is moderated by the North Atlantic Drift, a warm ocean current that transports heat from the tropics toward Western Europe [c1, c4]. This warm water interacts with the atmosphere, where prevailing south-westerly winds carry warm maritime air masses (often originating near the Azores or Western Africa) to the British Isles [t1, t5]. Simultaneously, the region is a mixing zone where this warm air meets cold, wet polar air masses from the Arctic and the Icelandic Low pressure system [t1, t3, t5]. This interaction of contrasting air masses and the heat provided by the North Atlantic Drift creates the UK's characteristic mild and changeable weather.
