  Questionário sobre a tarefa - Parte 1 <br/>
  <!--
    page 17
    After performing each of the tasks, you will be given a sheet of rating
    scales. You will evaluate the task by putting an "X" on each of the six scales
    at the point which matches your experience. Each line has two endpoint
    descriptors that describe the scale. Note that "own performance" goes from
    "good" on the left to "bad" on the right. This order has been confusing for
    some people. Please consider your responses carefully in distinguishing
    among the different task conditions, Consider each scale individually. Your
    ratings will play an important role in the evaluation being conducted, thus.
    your active participation is essential to the success of this experiment and is
    greatly appreciated by all of us.
    buscar: nasa tlx confusing scale rating performance "good" "bad"
    -->
  <br/>
  O objetivo deste questionário é capturar sua percepção sobre seu esforço para realizar a tarefa considerada.
  Para isso, por favor, leia a descrição dos seis (6) itens a serem analisados (logo abaixo à direita) e para cada um deles
  defina qual o grau de importância do item para você <i>clicando</i> na escala correspondente.
  Os valores crescem da esquerda (o menor é 0.5) para a direita (o maior sendo 10).
  Note que no item <i>Desempenho</i> a escala vai de "bom" à esquerda para "ruim" à direita.
