Atoms are composed of three main particles called electrons, protons and neutrons. We know that, the electrons are negatively charged particles whereas protons are positively charged and neutrons have no charge.

Hence, as the number of electrons and protons are equal and they are oppositely charged, the atom will have no charge as their charges cancel each other.

The next statement would be talking about the reason of the cease fire, therefore, P follows and S would be the concluding statement which makes a coherent paragraph. The correct formation would be, ‘Georgian loyalists and rebel forces agreed to a ceasefire today after a week of fighting in which 51 people were killed’.
