Input: Black people
From the years 1500 to 1850, an estimated 3.5 million captives were forcibly shipped from West/Central Africa to Brazil; the territory received the highest number of slaves of any country in the Americas. Scholars estimate that more than half of the Brazilian population is at least in part descended from these individuals. Brazil has the largest population of Afro-descendants outside of Africa. In contrast to the US, during the slavery period and after, the Portuguese colonial government and later Brazilian government did not pass formal anti-miscegenation or segregation laws. As in other Latin countries, intermarriage was prevalent during the colonial period and continued afterward. In addition, people of mixed race (pardo) often tended to marry white, and their descendants became accepted as white. As a result, some of the European descended population also has West African or Amerindian blood. According to the last census of the 20th century, in which Brazilians could choose from five color/ethnic categories with which they identified, 54% of individuals identified as white, 6.2% identified as black, and 39.5% identified as pardo (brown) — a broad multi-racial category, including tri-racial persons.

How much of the Brazilian population are descendants of slavery?
Output: more than half

Article: Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. Their effectiveness and easy access led to overuse, especially in livestock raising, prompting bacteria to develop resistance. This has led to widespread problems with antimicrobial and antibiotic resistance, so much as to prompt the World Health Organization to classify antimicrobial resistance as a "serious threat [that] is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country".

Question: What other medicine worked along antibiotics to eradicate diseases like tuberculosis?

Here is a question about this article: Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth.[citation needed] After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013.

What is the answer to this question: What are the more traditional industries that have existed in Portugal?
****
So... textiles, clothing, footwear and cork
