I was just wondering about tense concord. I believe [1], [3] and [4] stand, but [2] doesn't. Could you please help see this?<br/><br/>[1] I thought if it has eight legs, we didn't call it an insect; in fact, it is an insect.<br/><br/>[2] I thought if it has eight legs, we don't call it an insect; in fact, it is an insect.<br/><br/>[3] I thought if it has eight legs, we don't call it an insect, and I was right. It is not an insect.<br/><br/>[4] I thought if it has eight legs, we didn't call it an insect, and I was right. It is not an insect.<br/><br/>Hiro/ Sendai, Japan
