Read the text below and answer question.
Will we ever grow replacement hands?
Over the past few weeks on the BBC News website we have looked at the potential for bionic body parts and artificial organs to repair the human body. Now we take a look at "growing-your-own".
There is a pressing need. A shortage of available organs means many die on waiting lists and those that get an organ must spend a lifetime on immunosuppressant drugs to avoid rejection.
The idea is that using a patient's own stem cells to grow new body parts avoids the whole issue of rejection as well as waiting for a donor.
Dr Anthony Atala, director of the Institute for Regenerative Medicine at the Wake Forest Baptist Medical Center in North Carolina, US, has made breakthroughs in building bladders and urethras.
• Flat structures, such as the skin, are the simplest to engineer as they are generally made up of just the one type of cell.
• Tubes, such as blood vessels and urethras, which have two types of cells and act as a conduit.
• Hollow non-tubular organs like the bladder and the stomach, which have more complex structures and functions.
• Solid organs, such as the kidney, heart and liver, are the most complex to engineer. They are exponentially more complex, have many different cell types, and more challenges in the blood supply.
"We've been able to implant the first three in humans. We don't have any examples yet of solid organs in humans because its much more complex," Dr Atala told the BBC.

Questão 30 242316UESB Caderno 1 2010
The mountainous region of Sa Pa in northern
Vietnam is an invaluable storehouse of medicinal
plants — many of which have been used for centuries
by the local population. Sa Pa Essentials was
 established to protect these species from the increasing
threat of over-harvesting while at the same time boosting
incomes and improving lives within the community.
Having identified active ingredients through
traditional knowledge as well as scientific testing, Sa
 Pa Essentials encourages sustainable cultivation of
medicinal species. It then extracts, processes and
markets essential oils from the plants, ensuring at every
stage that the communities’ intellectual property rights
 Do Thi Thu Ha, Director of Sa Pa Essentials, said
that products processed from herbs are brand new ones
which have never existed in the market before. The
company’s herbal products are available in New Zealand,
Japan and the Republic of Korea, not in Vietnam. The
 price for an essential oil vial is around $8 abroad.
However, Ha said that these products will soon be sold
in Hanoi and in Sa Pa town.

( ) combines traditional knowledge with scientific procedures.
( ) prevents the medicinal plants from being collected exhaustively.
( ) helps the local population lead a better life.
( ) exports young plants of their medicinal species to many parts of the world.
According to the text, the correct sequence, from top to bottom, is
