Question : Comprehension: Read the passage and answer the questions that follow. Greek religious traditions encompassed a large pantheon of gods, complex mythologies, rituals, and cult practices. Greece was a polytheistic society and looked to its gods and mythology to explain natural mysteries as well as current events. Religious festivals and ceremonies were held throughout the year, and animal sacrifice and votive offerings were popular ways to appease and worship the gods. Religious life, rituals and practices were one of the unifying aspects of Greece across regions and poleis (cities, or city-states, such as Athens and Sparta). The Greek gods were immortal beings who possessed human-like qualities and were represented as completely human in visual art. They were moral and immoral, petty and just, and often vain. The gods were invoked to intervene and assist in all matters large, small, private, and public. City-states claimed individual gods and goddesses as their patrons. Temples and sanctuaries to the gods were built in every city. Many cities became cult sites due to their connection with a god or goddess and specific myths. For instance, the city of Delphi was known for its oracle and sanctuary of Apollo, because Apollo was believed to have killed a dragon that inhabited Delphi. The history of the Greek pantheon begins with the primordial deities Gaia (Mother Earth) and Uranus (Father Sky), who were the parents of the first of twelve giants known as Titans. Among these Titans were six males and six females. The males were named Oceanus, Hyperion, Coeus, Crius, Iapetus, and Kronos. The females were named Themis, Mnemosyne, Tethys, Theia, Phoebe, and Rhea. Kronos eventually overthrew Uranus and ruled during the mythological Golden Age. Over time, he and Rhea had twelve children who would become the Olympian gods. However, Kronos heard a prophecy that his son would overthrow him, as he did for Uranus. In an effort to avert fate, he ordered Rhea to allow him to devour each of the children upon their birth. Best known among the pantheon are the twelve Olympian gods and goddesses who resided on Mt. Olympus in northern Greece. Zeus, the youngest son of Rhea and Kronos, was hidden from his father instead of being swallowed. Once he became a man, he challenged his father’s rule, forcing Kronos to regurgitate the rest of his swallowed children. These children were Zeus’s siblings, and together they overthrew Kronos, making Zeus the father of gods and men. Question: How did Zeus bring back his siblings?
Option 1: by challenging and slaying Crius
Option 2: by reviving them with an elixir
Option 3: by making Kronos vomit the swallowed children
Option 4: by worshipping the sanctuary of Apollo

Solution : The correct choice is the third option.
Explanation: Zeus, after reaching adulthood, challenged his father, Kronos, which led Kronos to regurgitate the children he had swallowed. This act allowed Zeus's siblings to be restored, and together they overthrew Kronos,
