"Marin drank heavily while she was pregnant, so it is possible that the infant has fetal alcohol spectrum disorder."

This disorder is characterised by several physical features including a smaller head perimeter, <span>low body weight,</span> and also several other cognitive and sensory deficiencies.

Answer:

  1. Alaska
  2. Washington
  3. Hawaii
  4. California
  5. Oregon

Explanation:

Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range.  Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state.  Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.
