Why did the Hittites and others migrate from Central Asia to Mesopotamia?

A- the needed more land for growing populations

B- they were enlarging their empire

C- the Persian army drove them out

D- climate change brought a mini ice age to Asia

My guess is D
But I am really unsure.

I don't think D is the best answer. Both A and B are better answers.

Go with whatever your book says.

It says this:

Some of the Indo-European groups migrated
south and east. One group, the Aryans, settled in
present-day Iran. Later, some of the Aryans broke
away and migrated farther east, to India. Other
Indo-Europeans migrated west, toward Europe.
Among them were the Hittites, who settled in
Asia Minor. Another group, the Celts, kept mov-
ing through western Europe until they reached
the British Isles. The Irish of today are descended
from the Celts.
As the Indo-Europeans divided and moved
in different directions over vast distances, their
languages grew apart. But linguists say that these
languages belong to the same language family,
which includes the main languages spoken today
in Europe, Iran, and India. The family resem-
blances between words in hundreds of different
languages allow us see the routes of one of his-
tory’s great migrations.
Push and Pull Factors
Migrations are usually caused by what historians
call
push
and
pull
factors. Push factors drive people
away from a place. Pull factors are what attract
them to another place.
The pull factor for the Indo-Europeans
became the wealthy cities of the settled south.
What was the push factor? It probably wasn’t some sudden catastrophe, since these migrations con-
tinued for about two thousand years. More than likely it was due to increasing population.
Instead of competing for pasture for their
herds, some clans roamed away in search of new
grazing grounds. They moved rapidly and far
because they may have been the first people to
domesticate and ride horses, perhaps as long ago
as 3500 B.C.
The Hittites
Sometime before 1700 B.C., the warlike Indo-Euro-
pean tribe, the Hittites, migrated into Asia Minor
and built their capital in the highlands. They knew
how to make iron, a secret they guarded closely
because it gave them a technological advantage
over their rivals. With their iron weapons, the Hit-
tites could win most battles. Hittite warriors drove
horse-drawn two-wheeled chariots, each of which
could carry three soldiers into battle—one to drive,
one to fight, and another to fight or shield his
comrades. Most chariots of this time carried only
two soldiers, so the Hittites had an edge.
In the sixteenth cen-
tury B.C., Hittite soldiers
marched to Babylon and
plundered the city. Later,
they built an empire
between the Black Sea and
the Syrian coast.
The Hittites were great
cultural borrowers. From
earlier inhabitants of Asia
Minor they learned to make
ceramic vases shaped like animals. From the Sumeri-ans they borrowed cunei-
form, which they adapted
to their own written lan-guage. They developed a
code of laws similar to Ham-murabi’s. Like the Mesopota-
mians, they decorated their public buildings with
rows of figures carved into rock. They worshipped
hundreds of gods because they accepted all the
local deities they came across.
Around 1275 B.C., the Hittites’ aggressive
empire building faltered when they battled to a
standstill against the Egyptian pharaoh Ramses II.
(You’ll read more about him later in this chapter.)
Soon after that, Hittite power began to fade, in
part because by this time many other people had
learned how to make iron, so the Hittites no longer
had an advantage.
The Hittite Empire crumbled around 1200 B.C.,
although historians aren’t sure why. The Hittites
might have been conquered by a wave of invaders
from lands west of the Aegean Sea. These so-called Sea People were sacking many coastal cities at the
time. Because few records from the time exist, we
know little about the Sea People who toppled the
Hittite Empire.

Thanks for posting it. One of my answers is obviously right. Which is it? A or B?

I meant to put A as my guess, I am sorry. The answer is A, thank you for correcting me! :)

Which sentence(s) state(s) that the Hittites needed more land for a growing population?

migrations continued for about two thousand years. More than likely it was due to increasing population.

Apparently you haven't read the section on the Hittites.

I did!! What do you think it is??

all yall are dumb asf the answer C

the answer is A
