Emma is conducting a research project on Texas during the 1840s and 1850s. Which keyword search should she use to find information about why slavery grew?

• “famous abolitionists”
• “demand for cotton”
• “Tejano culture and society”
• “Methodist preachers”

To find information about why slavery grew in Texas during the 1840s and 1850s, Emma should use the keyword search "demand for cotton."

Here's why:

1. "Famous abolitionists" may provide information about individuals who opposed slavery but may not necessarily explain why slavery grew in Texas during that specific time period.

2. "Tejano culture and society" may provide insights into the overall culture and society of Tejanos in Texas, but it may not solely focus on the reasons behind the growth of slavery.

3. "Methodist preachers" might provide information about the role of religion in Texas during that time, but it may not directly address why slavery grew in the region.

4. "Demand for cotton" is a more relevant keyword search because the growth of slavery in Texas during the 1840s and 1850s was largely driven by the increasing demand for cotton. By searching for this keyword, Emma can find information about how the demand for cotton influenced the expansion of slavery and its significance during that time period.

In summary, to understand why slavery grew in Texas during the 1840s and 1850s, Emma should focus her keyword search on "demand for cotton."
