Explicação
A とあれば B means 'if A is the case (or if it is for A), then B.' It is often used as in 子どものためとあれば (if it's for my child) or 必要とあれば (if necessary), and B usually shows the speaker's willingness to do something difficult or unusual. It is not used for simple time conditions or natural results. It is a formal expression.

If it's for his daughter, my father will drive to pick her up no matter how far it is.

Observações
B is not a guess or a description of a current state. とあって gives a real reason ('because of the special situation'), while とあれば is a hypothetical condition.

3「とあれば」の使い方がいちばん正しい文はどれですか。
Resposta e explicação
Resposta: 4 先生の頼みとあれば、喜んで引き受けます。
4 means "If it's a request from my teacher, I'll gladly take it on." 1 is a guess, 2 is a simple time condition, and 3 describes a state, so とあれば cannot be used.
