Problem: Text: In the spring of 492 BC an expeditionary force, to be commanded by Darius's son-in-law Mardonius, was assembled, consisting of a fleet and a land army. Whilst the ultimate aim was to punish Athens and Eretria, the expedition also aimed to subdue as many of the Greek cities as possible. Departing from Cilicia, Mardonius sent the army to march to the Hellespont, whilst he travelled with the fleet. He sailed round the coast of Asia Minor to Ionia, where he spent a short time abolishing the tyrannies that ruled the cities of Ionia. Ironically, since the establishment of democracies had been a key factor in the Ionian Revolt, he replaced the tyrannies with democracies.

Problem: Text: Red blood cells may be given as part of a blood transfusion. Blood may be donated from another person, or stored by the recipient at an earlier date. Donated blood usually requires screening to ensure that donors do not contain risk factors for the presence of blood-borne diseases, or will not suffer themselves by giving blood. Blood is usually collected and tested for common or serious Blood-borne diseases including Hepatitis B, Hepatitis C and HIV. The blood type (A, B, AB, or O) or the blood product is identified. This relates to the presence of antigens on the cell's surface. After this process, the blood is stored, and within a short duration is used. Blood can be given as a whole product or the red blood cells separated as packed red blood cells.

Problem: Text: Financial assistance in law refers to assistance given by a company for the purchase of its own shares or the shares of its holding companies. In many jurisdictions such assistance is prohibited or restricted by law. For example all EU member states are required to restrict financial assistance by public companies up to the limit of the company's distributable reserves, although some members go further, for example, Belgium, Bulgaria, France, and The Netherlands restrict financial assistance by all companies. Where such assistance is given in breach of applicable law it will render the relevant transaction void and may constitute a criminal offence.
