Question

Select the sentence in this passage that can be classified as a false statement. Although few humans per year are attacked by polar bears, any individual attack can be terrifying and even fatal. The warming of Arctic regions has allowed the intrusion of humans into the polar bears’ habitat, increasing the danger of harmful contacts. Remaining alert and using precautions can help humans avoid a negative encounter with a polar bear. Traveling together and staying close to the group can help humans avoid bear attacks. Certain weapons, including nonlethal ones such as pepper spray, are effective against polar bears. Once a bear has decided to attack, however, nothing can be done.

Answer 1

The false statement in the passage is that nothing can be done once a polar bear decides to attack, as measures such as nonlethal weapons can be used. Polar bears are threatened by global warming and the loss of sea ice, affecting their hunting practices. Grizzly bears' expanded range due to climate change overlaps with polar bears', leading to inter-species mating.

Step-by-step explanation:

The sentence in the passage that can be classified as a false statement is: "Once a bear has decided to attack, however, nothing can be done." This is not accurate, as there are measures one can take even if a polar bear decides to attack. For instance, using nonlethal weapons like pepper spray could help deter an attacking polar bear. Moreover, bears that have been fed by humans may become more accustomed to human presence and could seek out human habitations, potentially leading to dangerous encounters.

These polar bears are threatened primarily due to global warming, which is causing sea ice to melt. The sea ice is vital for them because it is where they hunt for seals, their main source of food. Additionally, the melting of sea ice may force polar bears to make more hazardous journeys to find sustainable hunting grounds.

Furthermore, climate change has also led to habitat overlaps between grizzly bears and polar bears. This overlap has been linked to an increase in inter-species encounters and even instances of viable hybrids known as grolar bears, signaling significant shifts in the ecosystems and natural behaviors of these species.

Answer 2

The sentence in this passage that can be classified as a false statement is The warming of Arctic regions has allowed the intrusion of humans into the polar bears’ habitat, increasing the danger of harmful contacts.

Step-by-step explanation:

This sentence can be considered as a false statement since it is not the human who is getting closer to the polar bears, it is because of all the pollution and the global warming that the bears are forced to enter to more civilized areas since they need to find a way to survive, the defrosting of ice is causing this reaction.
