Explanation:

Question 1

La ciencia tiene como objetivos investigar, explicar y predecir. El objetivo "to use data to support a particular point of view" no es un objetivo de la ciencia, ya que la ciencia busca objetividad, no apoyar una perspectiva particular.

Los científicos generan hipótesis usando imaginación (a), inferencia lógica (b) y conocimiento previo (c). Usar "un sentimiento" no es una forma de generar hipótesis científicas, ya que la ciencia es objetiva y basada en evidencia, no en sentimientos.

Las hipótesis científicas deben ser probables de testear (c). No garantizan que el experimento sea válido (a, ya que la validez del experimento depende de su diseño), no "prueban" las hipótesis (b, las hipótesis se testean, no se prueban de forma definitiva) y pueden contradecir hipótesis previas (d, la ciencia avanza con la revisión de hipótesis).

Answer:

c. to use data to support a particular point of view
