Final answer:
Words such as 'engrossed', 'stage', 'lead', 'cameo', and 'effects' are contextually appropriate fills for the sentences provided by a student relating to reading, acting, key roles in performances, special types of roles, and components of film production, respectively.
Step-by-step explanation:
The blanks given in the sentences provided by the student can be filled with words that are contextually appropriate and contribute to the overall comprehension of the sentences. The first blank could be filled with engrossed as it conveys someone being completely absorbed in reading their book.
For the second sentence, stage is a suitable word to indicate the student's desired acting career. The term 'male lead' fits the context for the third blank, referring to the primary actor in a film or play. A 'cameo role' adequately describes a small but special part in the text for the fourth set of blanks.
Lastly, the word effects completes the final sentence by referring to the visual and auditory components used to create the illusion of the film's setting, as in space travel.
