Excerpt from Stuff Matters

By Mark Miodownik

In the absence of copper, gold, and meteoric iron, our ancestors’ tools during the Stone Age were made of flint, wood, and bone. Anyone who has ever tried to make anything with these kinds of tools knows how limiting they are: if you hit a piece of wood it either splinters, cracks, or snaps. The same is true of rock or bone. Metals are fundamentally different from these other materials because they can be hammered into shape: they flow, they are malleable. Not only that, they get stronger when you hit them; you can harden a blade just by hammering it. And you can reverse the process simply by putting metal in a fire and heating it up, which will cause it to get softer. The first people to discover these properties ten thousand years ago had found a material that was almost as hard as a rock but behaved like a plastic and was almost infinitely reusable. In other words, they had discovered the perfect material for tools, and in particular cutting tools like axes, chisels, and razors. This ability of metals to transform from a soft to a hard material must have seemed like magic to our ancient ancestors.

In 1961 Professor Richmond from Oxford University discovered a pit that had been dug by the Romans in AD 89. It contained 763,840 small two-inch nails, 85,128 medium nails, 25,088 large nails, and 1,344 extra-large sixteen-inch nails. The hoard was of iron and steel and not gold, which most people would have found bitterly disappointing. But not Professor Richmond. Why, he asked himself, would a Roman legion bury seven tons of iron and steel? The legion had been occupying the advance headquarters of Agricola in a place called Inchtuthil in Scotland. This was at the outer reaches of the Roman Empire, and their mission was to protect its border from what they saw as the savage tribes who threatened it: the Celts. The legion of five thousand men occupied the region for six years before retreating and, in the process, abandoning their fort. They made great efforts to leave behind nothing that could help their enemies. They smashed all food and drink containers and burned the fort to the ground. But they weren’t satisfied with this. In the ashes were the steel nails that had held the fort together, and they were far too valuable to be left to the tribes that had driven them out. Iron and steel were the materials that enabled the Romans to build aqueducts, ships, and swords; they allowed them to engineer an empire. Leaving the nails to their enemies would have been as useful as leaving a cache of weapons, so they buried them in a pit before marching south.
Which line from the excerpt provides context that supports the meaning of the word malleable?

a) metals are fundamentally different

b) hammered into shape

c) they flow

d ) stronger when you hit them

Answer:

b) hammered into shape

Explanation:

According to the excerpt from Stuff Matters by Mark Miodownik, it is narrated that metals were a great discovery which replaced the use of stones and bones as they were easily malleable unlike the other previously used material.

The line from the excerpt that provides context that supports the meaning of the word malleable is "hammered into shape". This is because for a thing to be malleable, it means that it its shape can be easily altered.

Caring for Coral Reefs
Zachary Felton

Coral reefs are amazing underwater worlds. They cover about 186,000 square miles of ocean floor. They mostly exist in the warmest parts of the world. This is because coral reefs develop in shallow, warm water, usually near Land and mostly in the tropics. Coral reefs prefer temperatures between 70 and 85 degrees Fahrenheit. This is why they are found off the coasts of Africa, India, Australia, and Brazil Coral reefs closest to us are found off the coast of Florida.
