Final answer:
The Titanic was not booked to full capacity when it set sail; it carried about 2,224 people though it had a capacity for about 2,435 passengers. The statement in the question is false.
Step-by-step explanation:
The statement 'Titanic was booked to full capacity when it set sail on April 10, 1912' is false. Titanic was indeed the largest passenger ship built at that time, setting sail on its maiden voyage. However, it was not at full capacity. Though the Titanic could accommodate 2,435 passengers, it sailed with approximately 2,224 on board, counting passengers and crew.
For context, it is beneficial to note that the sinking of the RMS Lusitania in 1915 is a separate historical event where the ship was torpedoed by a German U-boat, resulting in the deaths of over 1,200 people, including 128 American citizens. The sinking of the Lusitania caused a public outcry and had significant implications for United States relations with Germany during World War I.
