Identify the sentence that contains errors in syntax.

The sentence with errors in syntax is the one that reads "Every day my brother older eats at home lunch." This sentence contains words in an order that disrupts the usual subject-verb-object flow in English, making it difficult to understand. The phrase "my brother older" incorrectly places the adjective "older" immediately after the noun without a clear relationship to the rest of the sentence. Additionally, the phrase "eats at home lunch" is awkwardly constructed, as “lunch” should logically follow the verb “eats” directly.

In contrast, the other sentences present a clear and standard construction of subject, verb, and object with adverbial phrases that enhance clarity. For example, "My brother eats lunch at home every day" and "At home, my brother eats lunch every day" both maintain a logical and natural flow of information, making them grammatically correct.
