Why can the us government be compared with a tree?

the us government can  be compared with a tree with a strong trunk and three branches. where trunk is american people with their ability to vote and branches: legislative, executive and judicial. the   legislative    branch  consists of the house of representatives and the senate. the executive  branch consists of the president, the vice president and 15 cabinet-level executive departments. the judicial branch consists of the supreme court and the lower federal courts, including the courts of appeal, federal district courts, bankruptcy courts, and courts of federal claims.

примерно так: поэтому правительство сша можно сравнить с деровом.

my parents and i like trevelling. this year we decided to go to venice. what can i say about this city? venice is one of the most magical places on earth.built entirely upon water its streets are really wide canals that run throughout the entire city. they carry people from one enchanted building to the next by way of handcrafted gondolas that float on the water like giant fallen leaves. it is a place where worries fade away as quietly as the rippling water.here the air is fresh and the people are free. all your free time you can enjoy this beautiful city. i felt in love with venice at the first moment. everybody must visit it.
