The legislative branch. Here is how it works: The legislative branch makes laws. The Senate and House of Representatives are both part of Congress, which is part of the legis â¦ lative branch. The executive branch enforces the laws and vetoes them. The president is part of the executive branch. Finally, the judicial branch judges people who break the law.
A century (from the Latin centum, meaning one hundred; abbreviated c.) is 100 years. Centuries are numbered ordinally in the English language along with many others (e.g. the 7th century AD/CE).
   The 20th century is the 20th group of 100 years, so it ended at  2000. If the century and the the digits they start with were the  same, I.E. the 19th Century was the years 1900 to 1999, then by  default the 1st Century would have to be the years 100 to 199.irst, the 1900s are slightly out of alignment  with the 20th century which is why peopl â¦ e confuse them. You are not  referring to the same years. So the 1900s refers to 1900 to 1999  whereas the 20th century refers to 1901 to 2000.
