There IS a flower on the table. Настоящее простое.
There WAS a flower on the table. Прошедшее.
То есть тебе просто надо заменить один глагол на другой.
He, she, it -> IS
They, we, you -> ARE
I -> AM
He, She, it, I -> was
THey, we, you -> were.
Со вторым заданием конечно немного сообразительности надо проявить. Если видишь, что там что-то про вчера, 3 года назад, какие результаты и так далее - это 100% прошедшее.
