For decades, the U.S. federal government strenuously tried to force Puerto Ricans to adopt English, to the extent of making them use English as the primary language of instruction in their high schools. It was completely unsuccessful, and retreated from that policy in 1948. Puerto Rico was able to maintain its Spanish language, culture, and identity because the relatively small, densely populated island was already home to nearly a million people at the time of the U.S. takeover, all of those spoke Spanish, and the territory was never hit with a massive influx of millions of English speakers like the vast territory acquired from Mexico 50 years earlier.
Does Puerto Rico have many English speaking residents?
****
The answer: the territory was never hit with a massive influx of millions of English speakers like the vast territory acquired from Mexico 50 years earlier.

The oldest method of studying the brain is anatomical, and until the middle of the 20th century, much of the progress in neuroscience came from the development of better cell stains and better microscopes. Neuroanatomists study the large-scale structure of the brain as well as the microscopic structure of neurons and their components, especially synapses. Among other tools, they employ a plethora of stains that reveal neural structure, chemistry, and connectivity. In recent years, the development of immunostaining techniques has allowed investigation of neurons that express specific sets of genes. Also, functional neuroanatomy uses medical imaging techniques to correlate variations in human brain structure with differences in cognition or behavior.
Until what century was brain studying mostly anatomical?
****
The answer: the middle of the 20th century,

Uncompressed audio as stored on an audio-CD has a bit rate of 1,411.2 kbit/s, (16 bit/sample × 44100 samples/second × 2 channels / 1000 bits/kilobit), so the bitrates 128, 160 and 192 kbit/s represent compression ratios of approximately 11:1, 9:1 and 7:1 respectively.
What would a bit rate of 160 correspond to in terms of compression ratio?
****
The answer: 9:1

North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was originally known as the Province of Carolina. The northern and southern parts of the original province separated in 1729. Originally settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements, but by 1718 the pirates had been captured and killed. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker, English and German immigrants. The colonists generally supported the American Revolution, as the number of Loyalists was smaller than in some other colonies.
North carolina and Sounth Carolina together were known as what?
****
The answer:
the Province of Carolina
