Final answer:
Cleft construction emphasizes specific parts of a sentence for deeper processing. For example, highlighting 'tree cutting for lumber' with a two-person crosscut saw in a discussion about short-term production.
Step-by-step explanation:
Cleft construction in English is used to emphasize a particular part of a sentence to make it the focus for the listener or reader, thereby affecting the depth of processing. An example of cleft construction in the context of production would be: 'It was tree cutting for lumber that we explored as a specific example of production in the short run, using a two-person crosscut saw.' Here, the phrase 'tree cutting for lumber' is highlighted as the main focus through this construction, prompting a deeper cognitive processing of the specific activity within the broader topic of production in the short run.
