Question

The image below, taken by the Hubble Space Telescope in 2012, shows a formation known as a circumstellar nebula.

Image courtesy of NASA

The image shows dust, distributed in a disk, orbiting around a central star. Some scientists believe that the process of planet formation could be occurring in this location. What statement best explains how scientists can use findings like these to better understand Earth’s Solar System?
A.
Scientists can better explain the formation of Earth's Solar System.
B.
Scientists can better predict how life will form on other planets of Earth's Solar System.
C.
Scientists can better predict gravitational changes through which Earth's Solar System will undergo.
D.
Scientists can better explain the formation of Earth's Solar System only from data gathered from planetary probes.

The best statement that explains how scientists can use findings like the circumstellar nebula observed by the Hubble Space Telescope to better understand Earth’s Solar System is:

**A. Scientists can better explain the formation of Earth's Solar System.**

This is because studying circumstellar nebulae and the processes involved in planetary formation around other stars can provide insights into how our own Solar System formed and evolved.

A student collects data on spring and neap tides, in feet, on four different days of the same year in Anchorage, Alaska. The graphs of her data are shown below.

Based on the data given, which statement is true about the tides?
A.
September 9 and 24 represent spring tides due to the added gravitational pull of the Sun.
B.
September 16 and October 2 represent neap tides due to the added gravitational pull of the Moon.
C.
September 9 and 24 represent neap tides due to the added gravitational pull of the Moon.
D.
September 16 and October 2 represent spring tides due to the added gravitational pull of the Sun

To determine which statement is true about the tides based on the provided data (even though I can't see the actual graphs), we can establish the basic principles regarding spring and neap tides:

- **Spring tides** occur when the Sun and the Moon are aligned, leading to enhanced gravitational pull and higher high tides and lower low tides. This happens during the full moon and new moon phases.

- **Neap tides** occur when the Sun and the Moon are at right angles to each other, resulting in lower high tides and higher low tides. This typically occurs during the first and third quarters of the Moon.

Given these definitions, we can evaluate the statements:

- If September 9 and 24 are higher tides than typically expected and closer to the new moon or full moon phases, they would be spring tides.
- If September 16 and October 2 are lower tides and corresponding to first or third quarter phases, they would be neap tides.

Without the exact graphs, we can't definitively choose the correct answer, but the logic above can guide us based on the tide patterns. Based on the definitions of spring and neap tides:

1. If September 9 and 24 have high tidal measurements, then A is true.
2. If September 16 and October 2 have low tidal measurements, then B or D may be true.
3. If September 9 and 24 have low tidal measurements, then C may be true.

Based on a logical assumption, if you know that September 9 and 24 were higher tides, then:

**A. September 9 and 24 represent spring tides due to the added gravitational pull of the Sun.**

If September 16 and October 2 were lower readings, then:

**B. September 16 and October 2 represent neap tides due to the added gravitational pull of the Moon.**

Please check the graphs to determine the respective tidal levels on those dates to select the true statement.
