Randy was the subject of discipline by his science teacher. It wasn’t the first time he had faced corrective action. In middle school, the record for detentions was held by him. This time, the options for Randy may be worse – he could even be expelled. Ten days at home were required for students who were expelled. Fun after-school activities like baseball wouldn’t be allowed, either.

Explanation:

According to the attachment, we are supposed to change passive voice into active voice. Sentences in the passive voice give emphasis to the person or thing receiving the action expressed by the verb. On the other hand, active voice emphasizes the one performing the action. To identify the passive voice in a sentence we must look for the verb to be as an auxiliary (in any tense) and the main verb in its past participle form.

In the passage we are rewriting, the sentences that contain passive voice are the following:

-  In middle school, the record for detentions was held by him.

- he could even be expelled.

- Ten days at home were required for students who were expelled.

- Fun after-school activities like baseball wouldn’t be allowed, either.

We can modify the sentences above using the active voice as is shown below:

-  In middle school, he held the record for detentions.

- they could even expel him.

- The school required ten days at home for students they expelled.

- They wouldn’t allow fun after-school activities like baseball, either.  

21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.
