Reading Comprehension Worksheet – Main Idea Answers

Here is the solution to the reading comprehension task, with explanations for each main idea.

#### Passage 1: The Piano
> *One of the most popular musical instruments is the piano. In the traditional musical instrument classification system of string, woodwind, percussion and brass, the piano falls into two categories. It is considered a string instrument because the sound comes from the strings inside the piano. It is also considered a percussion instrument, since the player strikes the keyboard, which signals an internal hammer to strike the strings.*

Main Idea:
✔ *The piano is classified as both a string and a percussion instrument because it produces sound through strings and is played by striking keys that activate hammers.*

Explanation:
The paragraph explains how the piano fits into two categories in music classification. The key details are:
- Sound comes from strings → makes it a string instrument.
- Player strikes keys, which triggers hammers → makes it a percussion instrument.
So, the main idea is that the piano belongs to two instrument categories due to its dual mechanism.

#### Passage 2: Irish Immigration to the U.S.
> *Irish immigration to the U.S. began during the early development of the American colonies. It is estimated that 200,000 Irish came to the US in the 17th and 18th centuries. The numbers swelled from 1820 to 1850 to almost 2 million Irish immigrants. Most of these were fleeing the potato famine from 1845 until 1852. Steady numbers continued to arrive during the late 19th and 20th centuries. Today, over 36 million Americans claim some level of Irish ancestry.*

Main Idea:
✔ *Irish immigration to the United States has been significant over many centuries, especially during the potato famine, and today millions of Americans have Irish heritage.*

Explanation:
This passage traces the history of Irish immigration:
- Started in colonial times.
- Increased dramatically during the potato famine (1845–1852).
- Continued through the 19th and 20th centuries.
- Resulted in over 36 million Americans claiming Irish ancestry today.
The main idea focuses on the scale and lasting impact of Irish immigration.

#### Passage 3: Water Conservation
> *As important as water conservation is, it is also very easy. A few simple habits can significantly reduce the water consumption of a household. One way to save water is to turn off the faucet when brushing your teeth. Also, don't allow faucets to drip; one drip can waste a large amount of water over a short period of time. Baths require less water than showers, so by taking a bath instead of a shower, you can reduce the amount of water your home uses. In the kitchen, running a dishwasher when it is completely full, rather than half full, can save up to 20 gallons a day. These simple changes will save water and save money.*

Main Idea:
✔ *Simple daily habits can greatly reduce household water usage and save money.*

Explanation:
The paragraph lists easy actions people can take to conserve water:
- Turn off tap while brushing teeth.
- Fix drips.
- Take baths instead of showers.
- Run dishwasher only when full.
All examples support the central point: small changes = big savings in water and money. So the main idea emphasizes practical, everyday water-saving habits.
