$\text{11. B}$

Bạn xem đoạn từ "Ever since đến actress" nha

Dịch: không bị giới hạn trong nhạc pop (do "she has shown herself to be a talented singer, dancer, songwriter and actress" nha)

$\text{12. D}$

Do có câu "...her mother was died from cancer" (mẹ cô ấy chết do ung thư) nên đây là different event (khó khăn) , và có câu "she seems to have gained such a strong personality..." ( cô ấy có một tính cách mạnh mẽ) nên là D (mạnh mẽ hơn sau những sự việc khó khăn)

$\text{13. A}$

Do có câu "..Madonna...has sold over... making her the most succesful artist alive" nên là A nha
