4 What does “it” in line 37 refer to? A the fitness routine B not socialising C giving up D smoking

Правильный ответ: B not socialising Объяснение: В предложении перед строкой 37 говорится: "She doesn't drink, smoke or socialise." А далее: "You have to give up a lot," says Sanchez. "It's difficult to meet people, but it doesn't worry me – love does not arrive because you look for it." Следовательно, "it" относится к отказу от общения (not socialising).
