This question tests your understanding of verb tenses and sentence structure in English. Let's analyze the sentence: "I _____ for a walk in the country and _____ a farm."

The sentence describes a past event. The first blank requires the main action (going for a walk), and the second blank requires what happened during that walk (seeing a farm). Both actions occurred in the past and are connected by "and," meaning they should be in the same tense.

Step-by-Step Analysis:

Step 1: Identify the tense needed. The sentence describes a completed action in the past, so we need the simple past tense.

Step 2: For the first blank, the correct past tense of "go" is "went."

Step 3: For the second blank, the correct past tense of "see" is "saw."

Step 4: Check the options:

• Went / see → Incorrect ("see" is present tense)
• Look / saw → Incorrect ("look" is present tense and doesn't fit the context of traveling)
• Went / saw → Correct (both in simple past tense)
• Go / saw → Incorrect ("go" is present tense)

Final Answer: The correct words to fill in the blanks are "went" and "saw." The complete sentence is: "I went for a walk in the country and saw a farm."

Related Concepts:

Simple Past Tense: Used to describe completed actions in the past. For regular verbs, we add "-ed" (e.g., walked, played). For irregular verbs, the form changes (e.g., go→went, see→saw).

Subject-Verb Agreement: The verb must agree with the subject "I." In past tense, most verbs have the same form for all subjects except "be" (was/were).

Important Rules:

1. When two actions are connected by "and" and happened in the same time frame, they should use the same tense.

2. Memorize common irregular past tense verbs: go→went, see→saw, eat→ate, take→took, etc.
