General Studies · Statement and Inferences

Direction: In the question below is given a statement followed by two inferences numbered I and II. An inference is something supposed or taken for granted. You have to consider the statement and the following inferences and decide which of the inferences is/are implicit from the given statement. Statement: Invasive species like Lantana camara and Senna spectabilis (weeping cassia) unleash a form of chemical warfare as their shed leaves decompose and change the chemical composition of the soil, rendering it unsuitable for the growth of other plant species. Lantana camara, introduced around 200 - 250 years ago as an ornamental plant, and plants like Prosopis juliflora (mesquite), were extensively propagated for their year-round greenery in arid and semi-arid regions of India. Inferences: I. There is a need to limit the growth of these invasive species as it reduces the suitability of the soil for other plants. II. These species need to be conserved as they can sustain in any region of India and create beautiful scenery.
