Difficulty: EasySupporting Claims with Evidence and Details

Given the following passage:

In 1925, at the age of fifty-five, Ynes Mexia embarked on her first botanical collecting expedition to Mexico. Over the next thirteen years, she traveled across North and South America, brave enough to confront harsh environments in search of rare plants. Her efforts resulted in the collection of nearly 150,000 plant specimens, including hundreds of new species. In particular, her discovery of a new genus of sunflower, *Mexianthus*, solidified her legacy in the scientific community.

The writer wants to revise the underlined portion ("brave enough to confront harsh environments") to provide the most specific, concrete details that support the claim that Mexia traveled through challenging and remote terrain. Which choice best accomplishes this goal?

  2. B
    encountering difficult weather; and traveling long distances far from home
  3. C
    collecting thousands of plant specimens that she later sent to museums and universities
  4. D
    having started her scientific career much later in life than most of her contemporaries

Answer
