Answer:
c The longhorns had been skittish, but Johnny Chillers—who was named for the old Chillers trail—sang to them whenever they started to spook to calm them down.
Explanation:
The best revision that corrects Sam's error in the use of dashes to set off a clause is option C because it correctly separates the group of words which indicates a pause to emphasize that what Johnny Chillers was named after.
An em dash is used to show a pause and are also used to separate groups of words and their usage can be interchanged with commas or hyphens.
Presently Britain had never been gone by the Romans and was totally obscure to them before the season of Caius Julius Caesar, who, in the year 693 after the establishment of Rome, yet the sixtieth year before the Incarnation of our Lord, was diplomat with Lucius Bibulus. While he was making war upon the Germans and the Gauls, who were separated just by the stream Rhine, he came into the region of the Morini, whence is the closest and most limited section into Britain. Here, having given around eighty boats of weight and quick cruising vessels, he cruised over into Britain; where, being first generally dealt with in a fight, and after that got in a tempest, he lost an impressive piece of his armada, no modest number of infantrymen, and all his mounted force. Returning into Gaul, he put his armies into winter-quarters and gave orders for building six hundred sail of the two sorts.
The correct answer is D. Japan
