The Trojan Horse is a tale from the Trojan War about the subterfuge that the Greeks used to enter the city of Troy and win the war. In the canonical version, after a fruitless 10-year siege, the Greeks constructed a huge wooden horse, and hid a select force of men inside. The Greeks pretended to sail away, and the Trojans pulled the horse into their city as a victory trophy. That night the Greek force crept out of the horse and opened the gates for the rest of the Greek army, which had sailed back under cover of night. The Greeks entered and destroyed the city of Troy, decisively ending the war. Therefor the advice is saying beware of tricks by your enemy and target.
<em>A. A measure that allowed the U.S. government to intervene in Cuban affairs.</em>
Explanation:
The Platt Amendment was made in 1901 and had it so all treaties that were brought to Cuba had to be approved by the United States.
The United States could now intervene in Cuban affairs whenever they wanted, they wanted to protect certain interests that were on Cuba and protect the Cuban independence. The United States could also now lease or even buy certain parts of Cuban land for naval bases or even coaling stations to power certain things.
Many Cubans actually approved of the Platt Amendment, as many felt more protected and safer.
