Q. Pages: How do you adjust letter-spacings in Pages?

Hi, I have a problem with letter-spacings in Pages. With the default settings, Pages puts too wide spacings on spaces and letters like below.

I believe it's because Pages doesn't allow word-breaks. That might be why long words that don't fit in the respective line are pushed down to the next line, only to make the previous line stretched wider.

Is there any way Pages can apply the default spacings between letters like below?
