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.
The author draws a contrast between metals and other materials in all of the following EXCEPT:

A) Flint, wood, and bone are more brittle.

B) Metals are reusable.

C) Metals are non-polluting.

D) Metals can be shaped into other objects.

Answers

Answer 1

Answer:

C) Metals are non-polluting.

Explanation:

According to the excerpt from Stuff Matters

by Mark Miodownik, it is narrated that metals were a very important discovery that helped shaped mankind forever. Our ancestors made use of stones, flints and bones but these materials had their limitations and could not be shaped into other forms. However, the discovery of metals solved this problem.

The author draws a contrast between metals and other materials in all of the following EXCEPT saying that Metals are non-polluting.

can someone write in Op-ed format about how immigration is an controversy?! i will give brainless
(edit): can u write it with over 350 words?

Answers

Answer:

Immigration seems to be the most prominent wedge issue in America. Senate Republicans and Democrats shut down the federal government over the treatment of immigrants brought to the U.S. illegally as children, also known as Dreamers. In his State of the Union address on Tuesday, President Donald Trump referred to U.S. immigration law as a “broken” system; one party clapped, the other scowled. This polarized reaction reflects a widening divide among voters, as Democrats are now twice as likely as Republicans to say immigrants strengthen the country.

These stories and others might make it seem like most Americans are anxious about the deleterious effects of immigration on America’s economy and culture. But along several dimensions, immigration has never been more popular in the history of public polling:

The share of Americans calling for lower levels of immigration has fallen from a high of 65 percent in the mid-1990s to just 35 percent, near its record low.

A 2017 Gallup poll found that fears that immigrants bring crime, take jobs from native-born families, or damage the budget and overall economy are all at all-time lows.

In the same poll, the percentage of Americans saying immigrants “mostly help” the economy reached its highest point since Gallup began asking the question in 1993.

A Pew Research poll asking if immigrants “strengthen [the] country with their hard work and talents” similarly found affirmative responses at an all-time high.

A Simple Flower Poem
by Trey Loker

A flower buds its petals of pink
It rises to the sky
Glowing and coloring the grass,
a light wind may pass,
and cool water flows to drink


A flower buds its petals of yellow
It's covered by trash
Coughing and wheezing a lot,
the wind cannot stop,
the trash from killing this fellow


A flower buds its poials of blue
Is crushed by cans
Without provocation
its freed from the suffocation
by a woman who loves so true


in which two ways is the story different from the poem?

A)The story involves a group of people working together towards a common goal
B) The story includes only one type of flower that was saved from pollution
C)The story involves discarded bags and cans covering delicate flowers
