2. MultiChoice

   Passage: Insects and mammals release chemical scents known as pheromones to mark trails, alert colony members to danger, and attract potential mates without making any audible sound. What is the central idea?

3. MultiChoice

6. MultiChoice

   Passage: Elephants emit low-frequency rumbles below the human hearing threshold. These infrasonic waves travel through ground and air for miles, enabling distant herds to coordinate movements. What is the central idea?

7. MultiChoice

   Passage: Weakly electric fish generate weak electric fields around their bodies. Shifts in these fields allow them to navigate muddy river bottoms and communicate species identity to nearby fish. What is the central idea?

8. MultiChoice

9. MultiChoice

   Passage: Male fireflies emit unique rhythm light flashes while flying. Females of the same species recognize the specific rhythm and flash back, facilitating mate recognition in the dark. What is the central idea?

10. MultiChoice

    Passage: Underground animals like mole rats and kangaroo rats thud their heads or feet against burrow walls. These seismic vibrations travel through soil, warning neighbors of predators or defending territory. What is the central idea?
