Answer: c. Phreatic eruption caused by the heating and expansion of groundwater.
Explanation:
The Kilauea is an active volcano in Hawaii that erupted very violently due to the buildup of steam in 1924. Lava from the volcano usually drains back to the main magma body beneath the sea via a sort of passage. When this happens, water is able to enter the passage and instantly become steam when it interacts with the lava and escape up the volcano.
This time however, when the lava drained, the walls of the passage collapsed on the passage thereby blocking it. The water that had now come into contact with the lava and had become steam were trapped. The steam kept building up and eventually forced the rocks outward very violently resulting in the explosion.

Answer:
Under the Gold Age leadership, citizens of the Abbasid Caliphate were also granted better access to health care, infrastructure and education than ever before. Heavy emphasis was placed on scholarship and learning during the Islamic Golden Age. It was during this time that the first public universities that granted degrees to graduates were founded in Baghdad, and the city welcomed scholars of all nationalities and religions so long as they made significant contributions to their fields. Trigonometry, the scientific method, and early observations that describe a process similar to evolution were some of the accomplishments made during this time.
Many of the works of Greek philosophers like Aristotle that we are able to read today were preserved during the Islamic Golden Age. Texts that were destroyed in their native counties were found when excavating the libraries of villas and palaces around Baghdad and major cities in Egypt.
