Directions: Use your advanced detective analytics to solve these comparisons. Determine how many times greater a digit's value is when it shifts position.
D1. SHIFT COMPARISON
Compare the value of the digit 6 in 650,420 to the digit 6 in 6,500,000.
The 6 in 6,500,000 is 10 times the value of the 6 in 650,420.
D2. SCALE INVESTIGATION
Compare the underlined digit in 3,240,195 with the underlined digit in 1,824,900.
The underlined 2 in 3,240,195 is 10 times the 2 in 1,824,900.
D3. DOUBLE AGENT REPORT
An agent claims that in the number 4,451,000, the underlined 4 on the left is exactly 10 times the value of the 4 next to it. Is the agent correct? Explain your analytical proof below.
Yes, the agent is correct. The left underlined 4 is in the Millions place (4,000,000) and the right underlined 4 is in the Hundred Thousands place (400,000). Since 4,000,000 is 10 times 400,000, the left 4 is indeed 10x larger.

✗ Wrong Way: 8,506 (That is eight thousand!)
✓ Correct: 8,000,506 (Perfect 7-digit millions layout!)
Notice that the Thousands Period is not mentioned at all!
To hold the millions place in position, we must load the thousands period with three zero guards: 000.
Also, "five hundred six" has no tens value, written as 506!

During an archaeological dig at the city park, Sofia uncovered a piece of smooth, gray pottery buried deep in the soil. She believed it was a piece of an old tablet used to log records long ago. She used a small, fine brush to clean the dirt away.
As she cleared the dust, she noticed a set of three parallel horizontal lines carved into the side. This identical stamp was used by copyeditors in ancient times to signify capitalization. Sofia smiled because she had found proof of early writing tools.

Prompt: Based on the details in "The Midnight Scout," explain how Leo's tools (the compass and flashlight) helped him succeed in his rescue mission. Support your answer with text evidence.
[R+A] Leo's tools helped him succeed in his rescue mission by letting him navigate through the dark storm and locate the horse.
[C] The story states that his flashlight provided a "steady beam of golden light" to watch for slippery rocks, and his compass pointed "directly North" toward where the horse loved to graze.
[E] This proves that without his flashlight to see and his compass to keep him headed North, Leo would have gotten lost in the dark rain and could not have found Barnaby.

Prompt: Based on the details in the selection, explain how lighthouse technology changed from ancient times to today. Support your answer with details from the passage.
[R+A] Lighthouse technology has changed significantly from ancient times to today, moving from open fires to specialized lenses and computers.
[C] The text explains that ancient builders used "huge coal fires inside large metal baskets," which was replaced in the 1800s by "curved glass lenses" called Fresnel lenses. Today, lighthouses are run by "computers, solar power, and bright light-emitting diode (LED) lamps."
[E] This shows that lighthouse light sources have become much brighter, more reliable, and completely automated over the years so that human keepers are no longer required to do hard physical labor.
