Answer: False

Explanation:

This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage

Angelina wants her text to look less crowded on the page, so she decides to decrease the length of the space the text occupies.
ratelena [41]

Answer:

She can go to the Layout tab and then to the Page setup command group to increase the margins of the page.

Explanation:

Because margin decides from the text should start ie. it decides how much space should be left on the top of the page, bottom, left and right. If you increase the margin automatically the amount of space in all the four sides gets increased and hence the contents gets automatically adjusted and the text will look better readable than before.

The crowd that it has created before automatically gets adjusted and will give a better look.
