Solid
1. Solid is one of the major states of matter. It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice or irregularly one.
2. The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.
3. The forces between the atoms in a solid can take a variety of forms. For example, a crystal of sodium chloride (common salt) is made up of ionic sodium and chlorine, which are held together by ionic bonds. In diamond or silicon, the atoms share electrons and form covalent bonds. In metals, electrons are shared in metallic bonding. Some solids, particularly most organic compounds, are held together with van der Waals forces resulting from the polarization of the electronic charge cloud on each molecule. The dissimilarities between the types of a solid result from the differences between their bonding.

Ответы:
+ A solid’s properties are quite different from those of a gas or a liquid due to its structure and the ability to resist.

 It has been an accepted fact that the quantity of atoms in a solid’s lattice is permanent.

 The existence of various solids can be explained by different types of their lattices.

 It is possible to change a solid’s state modifying its chemical bonds.

Утверждение «A solid’s properties are quite different from those of a gas or a liquid due to its structure and the ability to resist» («Свойства твердого тела совершенно отличны от свойств газа или жидкости») соответствует содержанию текста: «It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does» («Оно характеризуется жесткой структурой и сопротивлением на изменения формы или объема. В отличие от жидкости, твердое тело не течет и не принимает форму своего контейнера, не расширяется, чтобы заполнить объем целиком, как при этом ведет себя газ») (фрагмент 1).
