Answer:
1. The Titanic was known to be the safest ship that was ever built. It was believed that due to the way the ship was constructed, it was difficult for the ship to sink. The construction of Titanic began in March 1909 and was completed and launched in May 1911. It took 26 months to construct.
The below details from the excerpt supports that:
"She was touted as the safest ship ever built... This discrepancy rested on the belief that since the ship's construction made her "unsinkable", her lifeboats were necessary only to rescue survivors of other sinking ships"
2. What caused the ship to sink was when the ship struck an iceberg. The iceberg pulled into the ship and the ship began sinking.
Below is an excerpt that supports that:
"Four days into her journey, at 11:40p.m, on the night of April 14, she struck an iceberg."
3. The survivors of the tragic Titanic ship incidence were 705.
Below is an excerpt:
"The next morning, the liner Carpathia rescued 705 survivors"
