..but as he drove his lance-point into the sail the wind whirled it round with such force that it shivered the lance to pieces, sweeping with it horse and rider, who went rolling over on the plain, in a sorry condition.

Which definition matches the use of the word shivered in in the excerpt?

A. Stuck
B.Swung
C.Splintered
D. Surrenderd

Answers

Answer:

I'm aware there are multiple definitions to all of these words but I beleive that in the context given, splintered (C) is the correct answer.

Explanation:

Stuck= push a sharp or pointed object into or through (something)

Swung=move or cause to move back and forth or from side to side while suspended or on an axis

Splintered=break or cause to break into small sharp fragments.

Surrendered=cease resistance to an enemy or opponent and submit to their authority.

Key phrase:"shivered the lance to pieces"

why and how do humans exist when (eventually) we're all just gonna die, either by mass extinction or we just... die out?

Answers

Answer:

The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct.

Humans have vulnerabilities. Large, warm-blooded animals like us don’t handle ecological disruptions well. Small, cold-blooded turtles and snakes can last months without food, so they survived. Big animals with fast metabolisms – tyrannosaurs, or humans – require lots of food, constantly.

So we’re vulnerable, but there are reasons to think humans are resistant to extinction, maybe uniquely so. We’re a deeply strange species – widespread, abundant, supremely adoptable – which all suggest we’ll stick around for a while

When economists and policy makers talk about full employment, they do not mean 100 percent employment, rather they mean reaching a certain point that still leaves a portion of the labor force unemployed. Why is this the case and what are the kinds of unemployment that exist that do not allow us to reach 100 percent employment?

Answers

Employment cannot reach 100 percent because there is always unemployment. The kinds of unemployment that do not allow 100 percent employment are frictional, structural, cyclical and seasonal unemployment
