Which detail in "Trail Mail!" shows why a speedy mail service was so
important to the nation?

The Pony Express helped mails to deliver faster from one place to another in a short period.

Explanation:

Sending mails from one place to another was difficult, which took more than a week to send it to its destination. Letters sent through ships which regularly operated because of the supply of the goods. Homing pigeons, stagecoach, and railroads were some other methods to sent mails. To reduce the time a speedy mail service was introduced, which came to be known as the Pony Express. The Pony express sent letters from one place to another in a short time through a system of many riders that would gallop (ride horses) across the land to deliver mail. The fast mails help people living far from cities to be connected with recent activity and supported the military to maintain law and order in their stations.

Explanation:

free time is when all my homework and chores have been done for the day and i am "free" to do things that i enjoy doing.

usually i spend time watching television. as my favorite tv shows come on at specific times, i make sure that i finish my homework and chores well before the shows. otherwise i will have to miss them. mostly i manage to watch the shows but sometimes extra homework or chores may cause me to miss a show or two, but it is rare. anyhow if i know that i am definitely not able to catch a show in time, i will just set the video recorder to tape the show sothe evening when the weather is fine, i sometimes go for a stroll around the neighborhood with my friends. this is the time when most the neighbors have come home from work or school. we say hello to those whom we know. they are mostly friendly people and they acknowledge our greetings. once in a while we come upon unfriendly neighbors but we just ignore them and carry on. that i can watch it later.

the correct order is:

you're your own worst enemy:

they're going to say what they say, but

their opinions aren't holding you

back. it's your self-defeatist

attitude that's keeping your work

from getting its due.
