Final answer:
The student's question involves filling in the blanks with 'cassava' for manioc and 'potato' for the crop in Peru, two key domesticated plants in Ancient America.
Step-by-step explanation:
The other domesticated plants in Ancient America that the question refers to include manioc, also known as cassava, which is a starchy root cultivated by the Tainos, Caribs, and Chibchas in the tropics. In Peru, the important domesticated plant was the potato. Therefore, the correct option to fill in the blanks is 'cassava' for manioc and 'potato' for the crop in Peru.
Manioc, a staple crop, was developed from the trees' poisonous roots in the Amazon region. To remove the toxins in manioc, Amazonian tree farmers had to develop specific technologies that included boiling, drying, and chemical leaching, which made the roots safe for consumption. Similarly, the potato was a vital crop that was domesticated in the Andean region by selecting and cultivating certain varieties that could withstand different growing conditions.
Given the above discussion, the appropriate completion to the sentence in question would be: 'manioc, also called cassava, a starchy root cultivated by the Tainos, Caribs, and Chibchas in the tropics, and the potato in Peru.'
