How to make two vertical rows of checkboxes pararell to each other? android

This is part of my code. Everything would work perfectly if not that some of the checkboxes' texts take two lines and some one line. How do I make them pararell to each other?

            `<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <LinearLayout
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:orientation="vertical">
                <CheckBox
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/answer9_1"
                    android:textAppearance="?android:textAppearanceMedium"/>

                <CheckBox
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/answer9_2"
                    android:textAppearance="?android:textAppearanceMedium"/>

                    android:text="@string/answer9_7"
                    android:textAppearance="?android:textAppearanceMedium"/>

                <CheckBox
