A New Way of Fish Farming
The new type of water has （ 27 ） .
Conventional methods
Freshwater fish farming： （ 28 ） in Southeast Asian countries
Saltwater fish farming： highly （ 29 ） worldwide
Advantages of the new type of water
● Saltwater fish can be raised in landlocked countries.
● Fish growth is faster.
● Fish health is （ 30 ） .
● It can be （ 31 ） for plant farming.
What if there was a way to raise saltwater fish in countries with no access to oceans or seas？ Japanese researchers are experimenting with a new type of water in Mongolia and other countries. It is made by adding selected minerals found in seawater to fresh water. The result is a mixture that is lower in salt and mineral content than seawater. Before we dive in deeper, let’s review what we know about fish farming.
Fish farming is an important part of global efforts to fight food shortages. While freshwater fish farming is common in Southeast Asia, saltwater fish farming has grown rapidly over the past 30 years. Saltwater fish farming, which produces fish such as salmon and tuna, generates great financial rewards in the international market.
That’s where the advantages of using this new water come in. In landlocked countries like Mongolia, which have no access to an ocean, raising saltwater fish on inland farms could become a valuable source of income and nutrition for local populations. In fact, even wealthier landlocked countries that already eat a lot of seafood might consume more if fish were raised locally.
Fish raised in this new water grow faster and get fewer deadly diseases than those in the wild.
These factors contribute to commercial success.
Furthermore, this new type of water has other benefits. Because of the way it’s made, that same water can be used to grow salt−tolerant plants like tomatoes, instead of being wasted after the fish have been raised. This saves water in areas where water is scarce. More research is needed, but early results show that this special type of water may be the wave of the future.

May：Which do you think has the stronger influence on fish consumption, GDP or geography？
Joe：Good question. Switzerland and Luxembourg have no direct ocean access, but this graph shows the consumption of fish and seafood there is comparatively high. Like Japan, they are both higher−GDP countries.
May：Interesting. Madagascar and Haiti are island countries, but there, consumption is relatively low.
Joe：Well, they are both lower−GDP countries, like Mongolia.

講義、JoeとMayの会話及び図表の内容からどのようなことが言えるか、最も適切なものを、選択肢のうちから一つ選びなさい。
- Because of the new water, fish and seafood consumption is higher in Switzerland than Mongolia.
- Fish farming with the new water could increase fish and seafood consumption even in countries like Luxembourg.
- In countries with high fish and seafood consumption, fish can be raised using water that has grown tomatoes.
- Low−GDP island countries consume more fish and seafood than high−GDP landlocked countries.
正解！素晴らしいです

各選択肢を読み、関連のある本文、会話内容、図表を確認し、答えを導き出していきます。
会話の内容は
メイ：魚の消費により大きな影響を与えるのは、GDPか地理のどちらだと思う？
ジョー：いい質問だね。スイスやルクセンブルクは、海への直接的なアクセスはないけど、このグラフは海鮮類の消費量は比較的高いと示している。日本のように、この２つはGDPが高い国なんだ。
メイ：面白い。マダガスカル島やハイチは島国だけど、その消費量は比較的低い。
ジョー：うん、どちらも、モンゴルのように、GDPが低い国なんだ。
となります。
「新しい種類の水のために、スイスの海鮮類の消費量はモンゴルより高い。」
グラフより、海鮮類の消費量は、モンゴルよりもスイスが高いとわかります。
ただし２人の会話より、新しい水のためではなく、GDPの高さが要因であると言えます。
したがって誤りとなります。
正解 「新しい水での魚の養殖は、ルクセンブルクにような国でも海鮮類の消費量を増やす可能性がある。」
まずルクセンブルクについては、メイは
Switzerland and Luxembourg have no direct ocean access（スイスやルクセンブルクは、海への直接的なアクセスがない）
と述べています。
さらに本文には
In landlocked countries like Mongolia, which have no access to an ocean, raising saltwater fish on inland farms could become a valuable source of income and nutrition for local populations.
（モンゴルのような陸に囲まれ、海へのアクセスのない国では、内陸で海水魚を育てることが、価値ある収入源となり、地域の人々の栄養源となりうる）
とあります。
つまり、海鮮類の消費量が増える可能性があると言えます。
「海鮮類の消費量が多い国では、トマトを育てた水を使って、魚は育てられている。」
「トマト」をヒントにして本文には
that same water can be used to grow salt−tolerant plants like tomatoes, instead of being wasted after the fish have been raised.
（その同じ水は、トマトのような塩に耐性のある植物を育てるのに使うことができます。魚が育った後に、（水が）無駄になることなく。）
とあります。
魚を育てた水を植物に使うということになるため、本文の内容と逆となり、誤りです。
「GDPの低い国は、GDPの高い内陸の国よりも、海鮮類の消費量高い。」
２人の会話より、地理的状況に関係なく、GDPの高い国は、GDPの低い国よりも海鮮類の消費量が高いとわかります。
したがって誤りです。
選択肢から、関連のあるもの（本文、会話、図表）を見極めていきましょう。
