This is a classic Graphs and Tables question testing your ability to filter rows by multiple simultaneous conditions and compare relative vs. absolute trends. Here's how I'd break it down.

Key concept: Multi-condition row filtering + comparative trend analysis in G&T Data Insights.

Statement 1: "Between 2007 and 2011, shale gas made significant strides compared to other extraction methods."

Step 1 — Check shale gas values 2007–2011:
2007: 1.5 → 2008: 2.25 → 2009: 3.47 → 2010: 4.86 → 2011: 7.85
That's a 5x+ increase in 5 years. Now scan every other column across 2007–2011 — non-associated onshore went from 5.0 → 3.58 (down), associated with oil stayed flat, all others declined or grew marginally. Shale gas is the clear outlier by a wide margin.
→ Statement 1: YES

Statement 2: "In years when non-associated onshore < 3 MMcf AND tight gas < 6.5 MMcf, Alaska extraction remains the same."

Step 2 — Apply both filters simultaneously (this is where most people slip up — they check one condition at a time):
- 2020: non-assoc onshore = 2.97 ✓, tight gas = 6.4 ✓ → Alaska = 0.28
- 2022: non-assoc onshore = 2.85 ✓, tight gas = 6.49 ✓ → Alaska = 0.27
- 2019: non-assoc onshore = 3.05 ✗ (fails)
- 2021: tight gas = 6.44 ✓ but non-assoc onshore = 2.9 ✓ → Alaska = 0.27
- 2023: tight gas = 6.54 ✗ (fails)

Qualifying years: 2020, 2021, 2022. Alaska values: 0.28, 0.27, 0.27 — not all the same.
→ Statement 2: NO

Common trap: Students check only one condition and incorrectly shortlist more years, or assume "remains the same" can be approximate. The question requires exact equality.

Statement 3: "In the 5 years with maximum total production, no method contributed its ever-highest production in all those years."

Step 3 — Identify top 5 total years: 2023 (27.75), 2022 (27.39), 2021 (26.94), 2020 (26.61), 2019 (26.31).

Step 4 — Check if any column hits its all-time high within this window. Shale gas all-time high = 12.18 in 2023, which is one of the top 5 total years. So at least one method (shale gas) did hit its ever-highest production during a year in that top-5 set.
→ Statement 3: NO

Final answers: Yes / No / No

Takeaway: For multi-condition G&T filter questions, build your qualifying row list before reading what the statement claims — it cuts your work time in half and eliminates the most common filtering errors.

Let's walk through all three statements using the table data.

Statement 1 (Yes):  Between  2007  and  2011 , shale gas grew from  1.5  to  7.85  million MMcf — an increase of  6.35 , or roughly a  423%  jump. Now compare every other method over the same period:
- Non-associated onshore:  5.00  →  3.58  (declined)
- Associated with oil:  1.95  →  2.08  (barely changed)
- Coal bed methane:  1.78  →  1.71  (declined)
- Non-associated offshore:  2.37  →  1.58  (declined)
- Alaska:  0.41  →  0.35  (declined)
- Tight gas:  6.26  →  5.86  (declined)

Shale gas clearly made the most significant strides.   Answer: Yes

Statement 2 (No):  We need years where BOTH non-associated onshore is below  3.0  AND tight gas is below  6.5 . Scanning the table:
-  2020 : onshore =  2.97  (below  3 ) and tight gas =  6.40  (below  6.5 ) → qualifies
-  2021 : onshore =  2.90  and tight gas =  6.44  → qualifies
-  2022 : onshore =  2.85  and tight gas =  6.49  → qualifies
-  2023 : onshore =  2.77  but tight gas =  6.54  → does NOT qualify ( 6.54  is not below  6.5 )

So the qualifying years are  2020 ,  2021 , and  2022 . Alaska extraction in those years:  0.28 ,  0.27 ,  0.27 .  These are NOT all the same  —  0.28  differs from  0.27 .   Answer: No

Statement 3 (No):  First, find the five years with the highest total production:
 1.   2023 :  27.75 
 2.   2022 :  27.39 
 3.   2021 :  26.94 
 4.   2020 :  26.61 
 5.   2019 :  26.31

The statement claims that NO method hit its all-time highest production in any of these five years.  But look at shale gas  — its all-time peak is  12.18  in  2023 , which IS one of these five years. Similarly, tight gas peaks at  6.54  in  2023 . So the claim is false — at least two methods achieved their ever-highest production during these top- 5  years.   Answer: No

Yes	No	Statement
		Between 2007 and 2011, U.S. shale gas production made significant strides compared with other gas extraction methods.
		In the years when the production of natural gas in the US from non-associated onshore extraction is below 3 million MMcf cubic feet and that from tight gas extraction is below 6.5 million MMcf cubic feet, the production of natural gas from its extraction from Alaska remains the same.
		In the five years that received the maximum contribution to the production of natural gas by all the listed methods, no method contributed its ever-highest production in all the listed years to the production of natural gas.
