"the chisholm trail" and the "goodnight-loving trail" are two prominent examples of a) cattle trails heading out of texas. b) routes used during the trail of tears. c) patterns of migration of american bison. d) the railroad lines that stretched westward.

The correct answer is A, as both the Chisholm Trail and the Goodnight-Loving Trail are two prominent examples of cattle trails heading out of Texas.

The Chisholm Trail was, in the second half of the nineteenth century in the United States of America, one of the many trails traced by hunters and cattle traders that allowed to reach the central states of the Union starting from Texas (where the railways had not yet reached), that is to transport the animals destined for consumption on the east coast of the United States, to the main railway junctions, already existing further north, in the central states. One of the hunters in question took the name of the trail: Jesse Chisholm, a half-breed Cherokee who traded habitually with the natives and had created with them some points of exchange and commerce along the way.

The Goodnight Loving Trail was a herd path in the United States for the cattle drive from Texas and New Mexico to the loading yards in the north.

The trail was particularly used in the late 1860s, to lead large herds of Texas Longhorn cattle from pasture in the south of Texas to Colorado. It was named after the cattle breeders Charles Goodnight and Oliver Loving, who drove their first common flock along this route in 1866.
