Preventing automatic measure break

[Javier Ruiz-Alma]

I'd like the engraving to stick to three measures per line.

 

One line is automatically breaking with only two measures.  Best I can tell, it's because of lyrics text.

 

Is there a way to:

a) force these three measures to stay together, or

b) globally force all lyric text to a (smaller) font size?
 

Thank You
