Final answer:
The text structure is 'cause and effect,' as the statement suggests that weather changes might lead to allergy troubles. Allergies involve the body's mistaken immune response to harmless substances as threats, leading to symptoms.
Step-by-step explanation:
The text structure in the statement “The allergy troubles you are experiencing may be due to the frequent weather changes this year” can be identified as cause and effect.
This structure is used when the author intends to describe a situation where one or more causes lead to one or more effects. In this case, the “frequent weather changes” are being presented as the cause of the “allergy troubles.”
Understanding text structures is crucial in English as it helps us to comprehend and analyze the information being presented. In the context of allergies, which are a non-protective immune response, the cause (such as exposure to pollen, dust mites, and other allergens) leads to an effect (symptoms like coughing, sneezing, and itchy eyes).
These symptoms are the body's response to what it mistakenly perceives as a threat.
