Answer:
played; read
Step-by-step explanation:
In grammar it is important to keep coherence in the transitions of ideas. In the example "Yesterday she played solitaire while her brother reads a book." There are two sentences and a transition conjunction:
Sentence 1: "Yesterday she played solitaire " (which is expressed in past tense)
Sentence 2: "her brother reads a book" (Which is expressed in simple prsent tense)
Transition Conjunction: "While"
According to the adverb of time "yesterday" the whole sentence meaning and intention is expressed in past tense, so, in order to avoid a run-on mistake, both sentences must keep the past tense. The correct constructions of this sentence should be:
* "She played solitaire yesterday while her brother read a book."
* "While her brother read a book, she played solitaire yesterday." (Notice "," to connect both sentences).
* "Yesterday she played solitaire while her brother read a book."
