赤ちゃんの脳の中で何が起こっているのでしょうか。

Why do babies have such amazing abilities?
There is no established theory, but the study of the
brain gives us a clue. Brain development is the process
of creating and discarding connections among the
neurons. These connections are called synapses. The
development of synapses occurs at an astonishing rate
during babies' early years. At its peak, two million
synapses are created per second. By the age of three,
their brains have about 1,000 trillion synapses, many
more than they will ever need. Some of these synapses ¹0
remain intact, but many are gradually discarded.
Babies will keep enough synapses to use for the rest of
their lives.

1. c.
We can get a clue about why babies have amazing abilities by studying how synapses are created and discarded.
シナプスがどのように作り出され、破棄されるかを研究することで、なぜ赤ちゃんが驚くべき能力を持っているのかについての手がかりを得ることができる。

Why do babies have such amazing abilities? There is no established theory, but the study of the brain gives us a clue. Brain development is the process of creating and discarding connections among the neurons. These connections are called synapses.
赤ちゃんがなぜそのような驚くべき能力を持っているのか？確立された理論はないが、脳の研究が手がかりを与えてくれる。脳の発達は、ニューロン間の接続を作り出しては捨てるという過程である。これらの接続はシナプスと呼ばれている。

2. a.
Many of the synapses created during babies' early years are gradually discarded because babies won’t use them any longer.
赤ちゃんの初期に作られたシナプスの多くは、赤ちゃんが使わなくなるため、徐々に捨てられる。
← 本文8～12行目
By the age of three, their brains have about 1,000 trillion synapses, many more than they will ever need. Some of these synapses remain intact, but many are gradually discarded.
3 歳までに、赤ちゃんの脳には約 1,000 兆個のシナプスがあり、これは彼らが必要とするよりもはるかに多い。これらのシナプスの一部はそのまま残るが、多くは徐々に捨てられる。
