become / is

<Question>

In the following sentenses, there are some mistakes to be corrected. 

(A) The intensity becomes a minimum when the wavelength is 3.1 nm.

(B) When the temperature is large, the electrical resistivity increases.

(C) If x is small enough, the function becomes negligible.

<Hint>

「become」は変化(していく過程)，「is」は点のイメージ．

→ 「become, increase, etc」と「is」を同時に使うべきではない．

また接続詞にも注意が必要で「as」と「become,increase,etc」，「when」と「is」をそれぞれセットで使うべし

<Answer>

(A) The intensity becomes a minimum when the wavelength is 3.1 nm.

→ The intensity is a minimum when the wavelength is 3.1 nm.

or  The intensity becomes a minimum as the wavelength approches 3.1 nm.

(B) When the temperature is large, the electrical resistivity increases.

→ As the temperature becomes larger, the electrical resistivity increases.

(C) If x is small enough, the function becomes negligible.

→ If x is small enough, the function is negligible.
