Verb Alternations
The Middle Alternation
The middle alternation involves a change in a verb’s transitivity (e.g., Emily broke the laptop – Laptops break easily). Verbs that allow the middle alternation express the bringing about of a change of state in the verb’s object. Verbs like “pat,” “touch,” and “see” do not allow this alternation. It derives from a transitive verb, and the verb has active morphology. The subject corresponds to the logical object of a verb (i.e., patient). Transitive

Consumers provide factors of production to companies in exchange for rent.
Income: The value or price paid for the use of a productive resource in a given period. Income has three sources:

Spanish Dialects: A Linguistic Analysis
Like all languages, Spanish is not uniform, and dialects are defined by a series of features. The lines that determine these traits are called isoglosses but are often not clearly defined. However, these differences do not impede communication between speakers because the language has cultivated norms. Thus, we can differentiate between the Castilian of the Peninsula and America, although they share many traits.
On the peninsula, we can distinguish two zones:

Understanding Hazard Risk
Hazard risk is not equal to the value that achieves a risk. It depends on three factors:
- A hazard’s potential to be catastrophic, often occurring with quick escalation.
- Overexposure or the volume of population and property that may be affected.
- Vulnerabilities of a community to be damaged.
Prediction is based on statistical data that indicate whether a particular phenomenon is common in the area.
Prevention proposes the adoption of measures necessary for the event to have minimal
