Sent 5: established a patrician republic, which lasted five centuries.
Sent 6: In contrast to other Italian cities weakened by internal rivalries and unstable government, Rome drew strength from a solid aristocracy of consuls and senate ruling over plebeians proud of their Roman citizenship and only rarely rebellious.
Sent 7: Recovering quickly from the Gallic invasion of 390 b.c.
Sent 8: , the Romans took effective control of the peninsula by a military conquest reinforced by a network of roads with names that exist to this day: Via Appia, Flaminia, Aurelia.
Sent 9: All roads did indeed lead toand fromRome.
Sent 10: By 250 b.c.

Sent 13: The rest of Italy participated only by tax contributions to the war effort and minor involvement in commerce and colonization.

PROBLEM: Paragraph- Sent 1: Conduction is the transfer of thermal energy.
Sent 2: It occurs between objects or substances that are touching.
Sent 3: Thermal conductors are materials that are good conductors of heat.
Sent 4: Thermal insulators are materials that are poor conductors of heat.
Sent 5: Both conductors and insulators have important uses.
Sent 6: Convection is the transfer of thermal energy.
Sent 7: This occurs as particles move within a fluid.
Sent 8: The fluid may be a liquid or a gas.
Sent 9: The particles within the fluid transfer energy by moving from warmer to cooler areas.
Sent 10: They move in loops.
Sent 11: These loops are called convection currents.
Sent 12: Radiation is the transfer of thermal energy by waves.
Sent 13: These waves can travel through empty space.
Sent 14: When the waves reach objects, the heat is transferred to the objects.
Sent 15: Radiation is how the Sun warms the Earths surface.
Question: What is it called when thermal energy is transferred between 2 objects that are touching (A) Convection (B) Conduction (C) Induction (D) Radiation.

SOLUTION: B.

Sent 7: Durer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance.
Sent 8: This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective and ideal proportions.
Question: How old was Durer when he was patronized by emperor Maximilian I? (A) Thirties (B) Twenties (C) Teenage (D) Under 20 (E) 20 (F) 41.

SOLUTION:
B, E.
