Read the passage "Ants" in the box below.
Alona [7]

Answer:

C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.

Explanation:

Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).

However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.
