Fill in the correct form of the verb in brackets. The photographer _(take) pictures for three hours.

The sentence needs the present perfect continuous tense because the action started in the past and is still ongoing or has just finished. The correct form of the verb "take" in the present perfect continuous is "has been taking". So the completed sentence is: The photographer **has been taking** pictures for three hours. **Translation into Russian:** Фотограф фотографирует (или фотографировал) в течение трех часов.
