I cannot find the propositions, so I just define what an alpha particle is:
Alpha particles (or alpha rays) are a form of radiation emitted by unstable nuclei of great atomic mass (alpha decay). They consist of two protons and two neutrons combined into a particle identical to the helium nucleus, so they can be written 4He2+ (or 4α2+). (the nuclei will lose 2 positive charges and 4 atomic masses)
Unlike other particles, a Beta particle is the emission of an electron (or a position), and gamma rays (not a particle) is the emission of a ray photon very high energy light.
I hope this could help you with you answering the question.

The cerebral cortex appears to be wrinkly. Between the occipital lobe and the central sulcus is where the parietal lobe is located.
Where is the parietal lobe and what does it do?
One of the larger brain lobes, the parietal lobe is generally situated in the upper rear region of the skull. It interprets sensory data from the environment, primarily pertaining to touch, taste, and temperature. Damage to the parietal lobe may cause sensory impairment.
Where is the central sulcus ?
On the lateral and medial surfaces of the cerebral hemispheres, the central sulcus (also known as the Rolando's sulcus) divides the frontal and parietal lobes.

<span>The autumnal equinox takes place on the same date in the southern hemisphere as the spring equinox, since the seasons are in "opposite" order as the calendar falls. In this case, the autumnal equinox would fall on March 21, since this is the date of the spring equinox in the northern hemisphere.</span>
