Lithium-ion batteries lose capacity every time they are charged. The loss is not caused by the current itself but by tiny cracks that form in the electrode as lithium ions move in and out of it. Manufacturers slow the process by limiting how far a battery is discharged before it is recharged, which is why many devices report a full charge slightly below the cell's true maximum.

3. It can be inferred from the passage that ----.

• A) lithium-ion batteries lose capacity only when they are fully discharged
• B) electrode cracks are produced directly by the electric current
• C) charging speed is the main factor in battery ageing
• D) a device shown as fully charged may hold less than its cell could store
• E) manufacturers have eliminated capacity loss in recent models

4. Current guidelines recommend that antibiotics be ---- only after a bacterial infection has been confirmed, since unnecessary use accelerates resistance.

• A) inherited
• B) prescribed
• C) transmitted
• D) suspended
• E) diagnosed

• C) So that
• D) Since
• E) While

Hospital records are a poor guide to how common a disease is. They count only the patients who reach a hospital, and reaching a hospital depends on distance, cost and how alarming the symptoms appear. Mild cases therefore disappear from the record. Community surveys, which test a random sample of the population, usually find far more cases than hospital data suggest.

6. According to the passage, hospital records understate how common a disease is because ----.

• A) community surveys test only patients who are already ill
• B) hospitals rarely record the results of diagnostic tests
• C) they leave out patients with mild symptoms and those who cannot reach care
• D) mild cases cost more to treat than severe ones
• E) random sampling is less reliable than clinical records

7. City walls were expensive to build and even more expensive to keep. ---- A wall that could not be defended along its whole length was worse than no wall at all, because it gave the population a false sense of safety.

• A) Many medieval walls survive today as tourist attractions.
• B) Stone was usually quarried within a few kilometres of the town.
• C) Gates were closed at sunset in most European towns.
• D) A town therefore needed not only stone but a permanent garrison large enough to man the whole circuit.
• E) Trade routes determined where the largest cities grew.

8. Historians disagree about how far the reforms ---- the authority of the central government, since the surviving records were written by officials who had an interest in exaggerating their own success.

• A) translated
• B) strengthened
• C) inherited
• D) postponed
• E) resembled

Economic historians once treated migration as a simple response to wage differences: people moved from low-wage regions to high-wage ones. The model explained the direction of movement but not its volume. It predicted that the poorest workers would leave first, whereas records repeatedly show that emigration rises only after incomes at home have begun to grow. The reason is that moving costs money. Very poor households cannot afford the journey, and modest growth in income is what makes departure possible.

9. What does the passage mainly argue?

• A) Wage differences have no effect on where migrants choose to go
• B) Economic historians have abandoned the study of migration
• C) Migration records from earlier centuries are generally unreliable
• D) The poorest workers leave their region earlier than wealthier ones
• E) Rising incomes at home can increase emigration rather than reduce it
