- Paul Revere had warned villages that the redcoats were coming

- The Green Mountain Boys hid in the bushes and warned the Continental Army

The correct options are:

- Paul Revere had warned villages that the redcoats were coming
- When the British headed out, Americans hung two lamps as a warning signal

To determine why the colonial minutemen were so prepared for the arrival of the British in Concord, let's analyze each of the options provided:

1. When Washington saw the British, he fired three cannon shots sending a warning signal.
It is important to note that during the time of the Battle of Concord, George Washington was not present. While George Washington played a crucial role in the American Revolutionary War as the commander-in-chief of the Continental Army, he did not participate in the events leading up to the Battle of Concord. Hence, this option is not accurate.

2. Paul Revere had warned villages that the redcoats were coming.
This is a valid reason why the colonial minutemen were prepared. Paul Revere, along with Samuel Prescott and William Dawes, rode through the night of April 18, 1775, to warn the colonial militia that the British forces were advancing towards Concord. This warning allowed the minutemen to prepare for the impending arrival of the British troops, giving them time to assemble and plan their defense.

3. The Green Mountain Boys hid in the bushes and warned the Continental Army.
The involvement of the Green Mountain Boys in the events leading up to the Battle of Concord is not accurate. The Green Mountain Boys, led by Ethan Allen, primarily operated in the Vermont region and were not directly involved in warning the Continental Army or aiding in the defense against the British forces during the Battle of Concord. Hence, this option is not accurate.

4. When the British headed out, Americans hung two lamps as a warning signal.
This option is actually referring to the events that occurred during the Midnight Ride of Paul Revere. Paul Revere instructed Robert Newman to hang two lanterns in the Old North Church in Boston to signal that the British forces were moving by sea. This signal alerted the colonial militias, including the minutemen, to be prepared for the British approach. Therefore, this option is also a valid reason for the colonial minutemen being prepared for the arrival of the British in Concord.

In summary, the accurate options for why the colonial minutemen were prepared for the arrival of the British in Concord are:
- Paul Revere had warned villages that the redcoats were coming.
- When the British headed out, Americans hung two lamps as a warning signal.
