23) Pedir and servir are part of the -ir stem changing verbs. That means when using the verbs pedir and servir in present tense, all of the forms except for nosotros and vosotros have a change in the verb's stem from e to i. The nosotros and vosotros forms keep the e.

24) In Houston the aerospace center is a place where visitors can see can see the history of space exploration through exhibits and space missions.
