Answer Key: Texas Turning Point โ The Railroads Arrive
How to use this key
Answers are grouped by section and question number. Many items are open-ended; accept any response that shows correct reasoning even if the wording differs. Notes flag where more than one answer is defensible and list common misconceptions to watch for. Everything students need is in the packet, so answers should draw on the sources and timeline only. Estimated grading time: ~5โ7 min per packet.

4 Source observation of Source B.
Date represented: about 1885 (the 1880s).
Type of source: an original paraphrase / summary of a viewpoint โ not a genuine primary quotation. Full credit if the student recognizes it is not a real quote.
Proud detail: any of โ "everything changed," farmers can now ship cotton "in a morning," "new stores, a hotel, and new neighbors," or that the skipped town is "losing people to us." Accept any one.
5 Cause โ Event โ Effects chain.
Causes (before) โ accept any two supported by Source A / timeline, e.g.:
- Old travel by wagon, horse, and riverboat was slow and unreliable (a need for faster transport).
- Ranchers had to drive cattle for weeks to reach out-of-state railroads (demand to reach markets).
- After the Civil War, railroad companies laid track quickly / national markets were expanding.
- New towns grew up beside rail stations; skipped towns often shrank.
- Goods (cotton, cattle, lumber) shipped in days instead of weeks.
- Thousands of new settlers arrived; the Texas population grew rapidly.
6 Fact (F) / Interpretation (I) / Opinion (O).
b) I โ reasoned conclusion using "probably" ("caused nearby skipped towns to lose people").
c) O โ a personal belief/preference ("most exciting invention"); cannot be proven.
d) F โ checkable in Source A (cattle "driven north on foot to reach a railroad").
Fact = checkable; interpretation = reasoned from facts (often "because/probably"); opinion = personal belief.
7 Compare before/after shipping cattle + significance (short written).
8 Evaluate the claim "the railroad helped every town equally."
Explain CER (Q9) ~1โ2 min
9 Was the arrival of the railroads a turning point?
Defensible alternates: a student may frame the claim around a single main effect (population growth, town growth, or faster ranching/trade) and still earn full marks if two accurate pieces of evidence support it. A cautious student who argues the change was gradual can earn credit if they still cite evidence of clear before/after difference.
CER scoring rubric (3 points)
| Score | Claim | Evidence | Reasoning |
|---|---|---|---|
| 3 | Clear claim that it was a turning point, naming a main cause or effect. | Two accurate, relevant pieces from the sources and/or timeline. | Correctly links evidence to before/after change and explains why it is a turning point. |
| 2 | Claim stated, mostly clear. | One solid piece, or two with a minor error. | Some correct linkage but incomplete or a small misconception. |
| 1 | Vague or partly correct claim. | Evidence weak, off-topic, or not from the sources. | Little or flawed reasoning; no clear before/after link. |
| 0 | No/incorrect claim. | No evidence. | No reasoning. |

ACE Articulate / Connect / Extend.
Connect: the cited date/line must actually show change โ e.g., 1876 "new towns grow beside rail stations," 1888 "population grows sharply," or Source A "goods shipped in days instead of weeks."
Extend: any reasonable modern turning-point invention with a reason (e.g., the internet โ changed how people communicate; the smartphone; electric power). More than one answer is defensible; grade the reason, not the choice.
Watch Common misconceptions
- Cause vs. effect (Q5). Students often list an effect ("new towns grew") as a cause. Causes come before the event; effects come after.
- Fact vs. interpretation (Q6). A "probably/becauseโฆ" statement is usually an interpretation, not a plain fact. A preference ("most exciting") is an opinion.
- Treating Source B as a real quote. Source B is an original paraphrase of a viewpoint, not a genuine primary quotation โ the packet says so directly.
- "The railroad helped everyone equally" (Q8). The sources show winners and losers โ towns on the line grew, skipped towns shrank.
- Exact dates. The timeline dates are approximate markers of a sequence, not exact single-day events; grade the order and reasoning, not memorized dates.
Teacher follow-up based on likely errors
If many students misplace items in the Q5 cause/effect chain, do a 5-minute "before or after?" sort. If Q6 reveals fact/interpretation/opinion confusion, re-anchor with the Word Bank definitions and a few quick examples. If CER (Q9) evidence is thin, model citing a specific source line or timeline date aloud. Reinforcing that a turning point creates a clear before/after difference is the highest-value idea to revisit.
