Indiana's Lost River ....... underground for a distance of 22 miles
Correct Answer
A. Travels
Explanation
The correct answer is "travels" because the sentence is describing the action of Indiana's Lost River, which is a singular subject. Therefore, it requires a singular verb form, which is "travels." The verb form "traveling" is a gerund and cannot be used as the main verb in this sentence. "To travel" is an infinitive form and does not agree with the subject. "It travels" is the correct form to indicate that the river is the one doing the action of traveling underground.

Correct Answer

alternative
Explanation
The text discusses the changes in food production methods due to the increasing population and demand for food. In the past, farm animals lived natural lives in free-range conditions, but these methods were not sufficient to meet the growing population's demands. As a result, factory farming methods were introduced, along with the development of genetically engineered growth hormones, to increase food production. However, these methods have raised concerns about animal welfare and the quality of the food. Many people disagree with keeping animals confined in one building for their entire existence and argue for alternative farming methods.
