                                    Will we ever grow replacement hands?

There is a pressing need. A shortage of availableorgans means many die on waiting lists and those thatget an organ must spend a lifetime onimmunosuppressant drugs to avoid rejection.

The idea is that using a patient's own stem cells togrow new body parts avoids the whole issue ofrejection as well as waiting for a donor.

Dr Anthony Atala, director of the Institute forRegenerative Medicine at the Wake Forest BaptistMedical Center in North Carolina, US, has madebreakthroughs in building bladders and urethras.

He breaks tissue-building into four levels ofcomplexity.

• 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.

Analyze the following setence from the text:

“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.”

The expressions in bold print “the most complex” and “more complex” are examples of superlative and comparative structures. Select the alternatives that provide other examples of superlative and comparative sentences:

I. It has been selected as the best hospital in the state.

II. The treatment was highly expensive and extra medication was necessary.

III. The treatment is more effective on younger patients.

IV. Most of the time the effects of the medication are hard to notice.

Considere a citação a seguir, atribuída ao estilista Yves Saint Laurent (1936 - 2008), para responder à questão.

It pains me physically to see a woman victimized, rendered pathetic, by fashion.
