<span>Puck is a powerful supernatural creature, capable of circling the globe in 40 minutes or morphing unsuspecting mortals in a deep fog. Also known as Robin Good fellow, Puck would have been familiar to a sixteenth-century English audience, who would have recognized him as a common household spirit. But he's also a "puck," an elf or goblin that enjoys playing practical jokes on mortals. Although he is more mischievous than malevolent, Puck reminds us that the fairy world is not all goodness and generosity.</span>
The 4th one is correct! :)
1. Is B because they not talking about a specific gorilla
The phrase is from Keats's famous Ode on a Grecian Urn. Exact lines are:
<em>Not to the sensual ear, but, more endear'd,
</em>
<em>Pipe to the spirit ditties of no tone</em>
The author tells the pipes do not play to his or physical ear, but to the metaphorical ear or in his word of his "spirit". This spiritual ear is "more endear’d," or cherished in other words. The author asks the pipes to play "ditties of no tone,". It is songs without any note or sound and that songs do not exist in the real world.
