El compuesto que se usa para cultivar orquídeas se prepara con 3 kilogramos de musgo por cada 5 kilogramos de cáscara de pino. Si se van a preparar 12 kilogramos del compuesto, ¿cuántos kilogramos de cáscara de pino se necesitan?

\( \frac { 80 } { 50 } = - = - \)

\( \left. \begin{array} { l } { \frac { 3 } { 4 } - \frac { 2 } { 5 } = \frac { ( 5 ) ( 3 ) } { ( 5 ) ( 4 ) } - \frac { ( 4 ) ( 2 ) } { ( 4 ) ( 5 ) } = \frac { 15 } { 20 } - \frac { 8 } { 20 } = \frac { } { 20 } } \\ { \frac { 1 } { 4 } + \frac { 1 } { 2 } = \frac { 1 } { 4 } + \frac { ( L ) ( 1 ) } { ( ) ( 2 ) } = \frac { 1 } { 4 } + \frac { 2 } { 4 } = - } \end{array} \right. \)

Read the last sentence of "My Name Is Casares." Every once in a while, though, I'll notice in the reply [to one of my emalls] that the person's computer isn't able to read my accent and so, Instead, converts It Into a question mark, which somehow seems about right. What message or insight does the writer most likely intend to convey in this sentence? As you choose, consider the essay as a whole. Not every question we encounter in life has a definitive or certain answer. Much of what defines a person, such thes spelling of his or her name, is insignificant. Modern technology introduces "noise" into our experience, which makes it difficult to interpret the past. People are likely to have second thoughts about a serious decision, such as the decision to change the spelling of one's name.
