Text for questions 11 to 15.

1 Robotic surgery allows doctors to perform

many types of complex procedures with more

precision, flexibility and control than is possible with

4 traditional procedures. Robotic surgery is often

performed through tiny incisions, but sometimes it

is used in open surgeries.

7 Most often, a robotic surgery system includes

a camera arm and mechanical arms with surgical

instruments attached to them. The surgeon

10 controls the arms while seated at a control center,

called a console, near the operating table. The

surgeon sees a magnified, high-definition, 3D view

13 of the surgical site. The surgeon leads other team

members who assist during the operation.

Surgeons who use the robotic system find

16 that it can increase precision, flexibility and control

during the operation. The robotic system also

allows them to better see the site, compared with

19 traditional surgical methods. Using robotic surgery,

surgeons can perform delicate and complex

procedures that may be difficult or impossible with

22 other methods.

Robotic surgery often is done through tiny

openings in the skin and other tissues. This

25 approach is called minimally invasive surgery. The

benefits of minimally invasive surgery include:

fewer complications, such as surgical site infection;

28 less pain and blood loss; a shorter hospital stay and

quicker recovery; smaller, less noticeable scars.

Em uma turma de 40 estudantes de astronomia, a prova final consistiu em identificar no céu três constelações: Cruzeiro do Sul, Ursa Maior e Órion.

Verificou-se que:

1. 22 identificaram o Cruzeiro do Sul,
2. 18 identificaram a Ursa Maior,
3. 25 identificaram Órion,
4. 10 identificaram Cruzeiro do Sul e Ursa Maior,
5. 12 identificaram Cruzeiro do Sul e Órion,
6. 9 identificaram Ursa Maior e Órion,
7. 5 identificaram as três constelações.

Com base nesses dados, assinale a alternativa que apresenta corretamente o número de estudantes que não identificaram nenhuma das três constelações.
