Task 2. Define the type of semantic changes (lexico-semantic word-building):

А вдруг это ключ к цикаде

ты достал

Here are the semantic changes for each phrase:

1. **not without doubt**
- **Type:** Litotes
- **Explanation:** This phrase uses a double negative to express a positive statement, implying that there is some doubt.

2. **I’ve told you hundred times!**
- **Type:** Hyperbole
- **Explanation:** This phrase exaggerates the number of times something has been said to emphasize the speaker's frustration or impatience.

3. **marshal «a horse man» → “the highest military rank”**
- **Type:** Semantic Shift (Broadening)
- **Explanation:** The term "marshal" originally referred to a horse keeper or caretaker but has broadened to denote the highest military rank.

4. **the White House - the Administration**
- **Type:** Metonymy
- **Explanation:** "The White House" is used as a metonymy for "the Administration," meaning it represents the people and activities within the executive branch of the U.S. government.

These types of semantic changes are commonly observed in the evolution of language, reflecting how meanings of words and phrases can shift over time due to various linguistic and social factors.
