Answer:

One possible reason the narrator hears the sound of a heartbeat at this moment could be that he feels guilty for what he had done, so he might be hearing his own heartbeat and begin to panic, thinking that it's the old man's heartbeat he's hearing.

Head coverings were probably the first forms of apparel put on by early humans, probably for protection from rain and sun. Hats
alex41 [277]

Question:

Head coverings were probably the first forms of apparel put on by early humans, probably for protection from rain and sun. Hats for men have been considered proper fashion for centuries, but the popularity of hats, aside from baseball caps, declined in the second half of the 20th century. Now, in the early 21st century, the fashionable men's hat is seeing a resurgence in popularity. Led by styles such as the fedora and the panama, men are again choosing to add a "lid" to a stylish outfit when dressing up is required. Men are again finding that the hat is an accessory capable of expressing individuality and taste.

What is the best summary of this passage?

A. After a decline, hats are seeing a resurgence in popularity as part of a fashionable outfit.

B. After being popular for centuries, hats declined in popularity in the last half of the 20th Century.

C. Early humans first used hats to protect themselves from rain and sun, and hat popularity is growing.

D. Hat styles such as the fedora, the panama, and the baseball cap are popular.

Answer:

The best summary for the passage is option A) After a decline, hats are seeing a resurgence in popularity as part of a fashionable outfit.

Explanation:

The reason for that choice is because it hits on the two central points of the paragraph which are:

  1. Initially, head covering were essential due to their functionlity which is protecting the head from sun and rain. But then there was a decline in this practice in the second half of the 20th century
  2. Now the practice is becoming fashionable again

All the other options focus on one side of the story.

Cheers
