Problem: The power of parliament to pass bills was often thwarted by monarchs. Charles I dissolved parliament in 1629, after it passed motions critical of and bills seeking to restrict his arbitrary exercise of power. During the eleven years of personal rule that followed, Charles performed legally dubious actions, such as raising taxes without parliament's approval. After the English Civil War, it was accepted that parliament should be summoned to meet regularly, but it was still commonplace for monarchs to refuse royal assent to bills. In 1678, Charles II withheld his assent from a bill "for preserving the Peace of the Kingdom by raising the Militia, and continuing them in Duty for Two and Forty Days," suggesting that he, not parliament, should control the militia. The last Stuart monarch, Anne, similarly withheld on 11 March 1708, on the advice of her ministers, her assent from a bill for the settling of Militia in Scotland. No monarch has since withheld royal assent on a bill passed by the British parliament.
After which event was it decided that parliament should meet on a regular basis?
The answer is the following: English Civil War

Problem: There are three classes of components for oxide glasses: network formers, intermediates, and modifiers. The network formers (silicon, boron, germanium) form a highly cross-linked network of chemical bonds. The intermediates (titanium, aluminium, zirconium, beryllium, magnesium, zinc) can act as both network formers and modifiers, according to the glass composition. The modifiers (calcium, lead, lithium, sodium, potassium) alter the network structure; they are usually present as ions, compensated by nearby non-bridging oxygen atoms, bound by one covalent bond to the glass network and holding one negative charge to compensate for the positive ion nearby. Some elements can play multiple roles; e.g. lead can act both as a network former (Pb4+ replacing Si4+), or as a modifier.
What type of component can both make and change networks?
The answer is the following: intermediates
