I am confused about using 'being' in the middle of the sentences. For example I saw in an article in which 'being' was used like this:
However, the evidence points to placebo effects being more important than any neuro-pharmacological ones.
In that sentence why 'to be' was not used? What is the gramer rule used there? Is this a special structure?
Another sentence:
...... and we feel that incorporating them can help to broaden the scope of questions being examined.
In this sentence, 'being examined' seems to be reduction of relative clause, if so, why not used just 'questions examined'.
Any response would be appreciated.
