Answer:
Mongooses were introduced into most Caribbean islands between 1872 and 1900 in order to protect sugar cane fields from pit vipers.
Step-by-step explanation:
The sentences are combined by using the coordinating conjunction "in order to," which shows the reason or purpose for the introduction of mongooses. Additionally, the time frame of "between 1872 and 1900" is placed at the beginning of the sentence to provide context and set the stage for the explanation of why mongooses were introduced. By combining the two sentences in this way, the information is presented in a clear and concise manner that effectively conveys the purpose of introducing mongooses to the Caribbean islands.
