Question

which statement most likely explains the pattern of transmission rates in a warmed and normal climates?

1. people are more likely to travel during these months and transmit lungworms to muskox.
2. fewer predators hunt muskoxen during these months, leaving dense populations of muskox more likely to spread disease.
3. warmer weather during these months supports the growth and development of infective lungworms.
4. the snails that transmit lungworms cannot survive at high temperatures.

Explanation:

• (1) focuses on human behavior (travel) and transmission, but doesn't directly address environmental factors affecting transmission rates.
• (2) mentions predators and population density, not directly related to the core of transmission rate patterns in a warmed climate.
• (3) points out that warmer weather (a result of climate - warming in this context) supports the growth and development of infective lungworms. This directly links climate - related temperature change (warming) to the ability of the parasite (lungworms) to develop and thus affect transmission rates.
• (4) is about snail survival at high temperatures, which is not the main factor in explaining the pattern of transmission rates in a warmed climate as described in the context (the main focus is on lungworm development in a warmer environment).

Answer:

1. Warmer weather during these months supports the growth and development of infective lungworms.
