Answer:

1. in a paragraph that is left-aligned (the most common alignment), text is aligned with the left margin. In a paragraph that is justified, text is aligned with both margins.

2. A justified text increases the space between words to fill the entire line so that it is aligned with both the left and right edges. You can also change the alignment and justification settings in the paragraph dialog box.

3. A page layout document is like a canvas that you add text boxes, images, and other objects to, then arrange the objects on the page however you like. When you open a page layout document (or template), there is no body text area; to add text you need to add a text box and type in it. New pages must be added manually.
