Until November 2011, there was no specific law that punished fraud in public competitions. This made it difficult to frame fraudsters in any specific article of the Penal Code, causing them to escape Justice more easily. However, with the enactment of Law 12.550/11, it is considered a crime to improperly use or disclose confidential content of a public competition, with a penalty of imprisonment of 12 to 48 months (1 to 4 years). If this crime is committed by a public official, the penalty will increase by $\frac{1}{3}$.
If a public official is convicted of defrauding a public competition, his imprisonment sentence may vary from
(A) 4 to 16 months.
(B) 16 to 52 months.
(C) 16 to 64 months.
(D) 24 to 60 months.
(E) 28 to 64 months.
The manager of a parking lot near a large airport knows that a passenger who uses his car for home-airport-home trips spends about $\mathrm{R}\$ 10.00$ on fuel for this trip. He also knows that a passenger who does not use his car for home-airport-home trips spends about $\mathrm{R}\$ 80.00$ on transportation.
Suppose that passengers who use their own vehicles leave their cars in this parking lot for a period of two days.
To make the use of the parking lot attractive to these passengers, the value, in reais, charged per day of parking should be, at most,
(A) 35.00.
(B) 40.00.
(C) 45.00.
(D) 70.00.
(E) 90.00.

In a cafeteria, the success of summer sales are juices prepared based on fruit pulp. One of the best-selling juices is strawberry with acerola, which is prepared with $\frac{2}{3}$ of strawberry pulp and $\frac{1}{3}$ of acerola pulp.
For the merchant, the pulps are sold in packages of equal volume. Currently, the strawberry pulp package costs $\mathrm{R}\$ 18.00$ and the acerola one costs $\mathrm{R}\$ 14.70$. However, a price increase is expected for the acerola pulp package next month, rising to $\mathrm{R}\$ 15.30$.

The figure illustrates a game of Minesweeper, the game present in practically every personal computer. Four squares on a $16 \times 16$ board were opened, and the numbers on their faces indicate how many of their 8 neighbors contain mines (to be avoided). The number 40 in the lower right corner is the total number of mines on the board, whose positions were chosen at random, uniformly, before opening any square.
In his next move, the player must choose among the squares marked with the letters $P, Q, R, S$ and $T$ one to open, and should choose the one with the lowest probability of containing a mine.
The player should open the square marked with the letter

A designer draftsperson must draw a pan lid in circular form. To perform this drawing, she has, at the moment, only a compass whose leg length is 10 cm, a protractor, and a sheet of paper with a Cartesian plane.

A mountain bike type bicycle has a chainring with 3 gears and a cassette with 6 gears, which, combined with each other, determine 18 speeds (number of chainring gears times the number of cassette gears).
The number of teeth of the gears on the chainrings and cassettes of this bicycle are listed in the table.

The English physiologist Archibald Vivian Hill proposed, in his studies, that the velocity $v$ of contraction of a muscle when subjected to a weight $p$ is given by the equation $( p + a )( v + b ) = K$, with $a$, $b$, and $K$ constants.
A physiotherapist, with the intention of maximizing the beneficial effect of the exercises he would recommend to one of his patients, wanted to study this equation and classified it as follows:
Type of curve
Oblique half-line
Horizontal half-line
Branch of parabola
Arc of circle
Branch of hyperbola

The physiotherapist analyzed the dependence between $v$ and $p$ in Hill's equation and classified it according to its geometric representation in the Cartesian plane, using the coordinate pair ($p$; $v$). Assume that $K > 0$.
The graph of the equation that the physiotherapist used to maximize the effect of the exercises is of the type
(A) oblique half-line.
(B) horizontal half-line.
(C) branch of parabola.
(D) arc of circle.
(E) branch of hyperbola.
In a park there are two viewpoints of different heights that are accessed by a panoramic elevator. The top of viewpoint 1 is accessed by elevator 1, while the top of viewpoint 2 is accessed by elevator 2. They are at a distance that can be traveled on foot, and between the viewpoints there is a cable car that connects them which may or may not be used by the visitor.

Research shows that a driver who drives a car at a constant speed travels ``blindly'' (that is, without vision of the road) a distance proportional to the time spent looking at the cell phone while typing the message. Consider that this indeed happens. Suppose that two drivers ($X$ and $Y$) drive at the same constant speed and type the same message on their cell phones. Suppose, further, that the time spent by driver $X$ looking at his cell phone while typing the message corresponds to $25\%$ of the time spent by driver $Y$ to perform the same task.
The ratio between the distances traveled blindly by $X$ and $Y$, in that order, is equal to
(A) $\frac{5}{4}$
(B) $\frac{1}{4}$
(C) $\frac{4}{3}$
(D) $\frac{4}{1}$
(E) $\frac{3}{4}$
The result of an electoral survey, regarding voter preference in relation to two candidates, was represented by means of Graph 1. When this result was published in a newspaper, Graph 1 was cut during layout, as shown in Graph 2. Although the values presented were correct and the width of the columns was the same, many readers criticized the format of Graph 2 printed in the newspaper, claiming that there was visual harm to candidate B.
The difference between the ratios of the height of column B to column A in graphs 1 and 2 is
(A) 0
(B) $\frac{1}{2}$
(C) $\frac{1}{5}$
(D) $\frac{2}{15}$
(E) $\frac{8}{35}$
To decorate a children's party table, a chef will use a spherical melon with a diameter measuring 10 cm, which will serve as a support for inserting various candies. He will remove a spherical cap from the melon, and, to ensure the stability of this support, making it difficult for the melon to roll on the table, the chef will make the cut so that the radius $r$ of the circular section of the cut is at least 3 cm. On the other hand, the chef will want to have the largest possible area of the region where the candies will be attached.
To achieve all his objectives, the chef should cut the melon cap at a height $h$, in centimeters, equal to
(A) $5 - \frac{\sqrt{91}}{2}$
