The other ones don't make sense, radiant energy is electromagnetic and gravitational energy. You can't tell how many planets are in its solar system from only this information. The number of galaxies is also impossible to tell. The only other one that could perhaps make sense is the distance to the center of its galaxy. But, this again is disproved as one star can't tell you the position of the center.

Seismic waves are sent through the earth during earthquakes, and those
energy waves are what cause the ground to shake as they travel through
it.Seismic waves travel at different speeds when they pass through
different types of material, so by studying seismograms, scientists can
learn a lot about Earth's internal structure.Body waves are seismic
waves that travel through Earth's interior, or its 'body.' Surface waves
are seismic waves that travel through Earth's surface.Surface waves are
important, but they don't provide much information about what happens
below the surface. For this, we need to study body waves so that we can
see what Earth's 'body' is like.
There are two types of body waves, called P waves and S waves. P
stands for primary waves because these waves travel the fastest and are
detected first. S stands for secondary waves because these are slower
than P waves, arriving second on the seismogram.
The Sahel is located in Africa. It is the region in Africa that transitions from the Sahara to the Sudanian Savanna. It stretches across in the region from the West of Africa to the East and includes parts of Senegal, Mauritania, Mali, Burkina Faso, Algeria, Niger, Nigeria, Chad, Sudan, South Sudan, Eritrea, CAR, Cameroon, and Ethiopia.
